In mathematics, out of the few basic arithmetic operations, multiplication is one of the simplest ones. Multiplication can also be written as the repetitive addition of a particular number. It is used when there is a need to combine groups of equal sizes. It’s a tool used to learn how to multiply two numbers. Multiplication is used quite often in real life as it can prove to be really helpful while doing basic arithmetic calculations, multiplication is also used in many other fields, such as engineering and science. Engineers often use multiplication to calculate the total amount of materials needed for a construction project, and scientists use multiplication to find the total number of particles in a sample or to calculate the amount of a substance produced in a chemical reaction. In order to obtain the multiplication table of 144, we will repeatedly add the number 144. The number of times we add the composite number 144, we will get the multiplication or the product of 144. For example, if 144 is added 8 times, we get
144+144+144+144+144+144+144+144
which is equal to 1152. This can be also written as
144 \times 8 = 1152
Repetitive addition of a particular number can be represented by a multiplication table.to represent the multiplication table or times table for 144 we repeatedly add the number and obtain the final result. The following table represents the repetitive addition and the final results for the composite number 144:
144 \times 1 = 144 | 144 |
144 \times 2 = 288 | 144 + 144 = 288 |
144 \times 3 = 432 | 144 + 144 + 144 = 432 |
144 \times 4 = 576 | 144 + 144 + 144 + 144 = 576 |
144 \times 5 = 720 | 144 + 144 + 144 + 144 + 144 = 720 |
144 \times 6 = 864 | 144 + 144 + 144 + 144 + 144 + 144 = 864 |
144 \times 7 = 1008 | 144 + 144 + 144 + 144 + 144 + 144 + 144 = 1008 |
144 \times 8 = 1152 | 144 + 144 + 144 + 144 + 144 + 144 + 144 + 144 = 1152 |
144 \times 9 = 1296 | 144 + 144 + 144 + 144 + 144 + 144 + 144 + 144 + 144 = 1296 |
144 \times 10 =1440 | 144 + 144 + 144 + 144 + 144 + 144 + 144 + 144 + 144 + 144 = 1440 |
The following table contains the multiplication of 120 upto 20 times. If observed closely, a pattern can be observed in the 144 multiplication table, whereas 144 is an even number, the final products are also all even numbers.
144 | × | 1 | = | 144 |
144 | × | 2 | = | 288 |
144 | × | 3 | = | 432 |
144 | × | 4 | = | 576 |
144 | × | 5 | = | 720 |
144 | × | 6 | = | 864 |
144 | × | 7 | = | 1008 |
144 | × | 8 | = | 1152 |
144 | × | 9 | = | 1296 |
144 | × | 10 | = | 1440 |
144 | × | 11 | = | 1584 |
144 | × | 12 | = | 1728 |
144 | × | 13 | = | 1872 |
144 | × | 14 | = | 2016 |
144 | × | 15 | = | 2160 |
144 | × | 16 | = | 2304 |
144 | × | 17 | = | 2448 |
144 | × | 18 | = | 2592 |
144 | × | 19 | = | 2736 |
144 | × | 20 | = | 2880 |
Problem 1: Find the value of 144 \times 10 - 24
Solution: From the table, 144 \times 10 = 1440
= 144 \times 10 - 24
= 1440 - 24
= 1416
Thus the value of 144 \times 10 - 24 , is 1416
Problem 2: Find the value of 144 \times 6 + 230
Solution: From the table, 144 \times 6 = 864
= 144 \times 6 + 230
= 864 + 230
= 1094
Thus the value of 144 \times 6 + 230 is, 1094
Problem 3: Find the value of (8 \div 2) \times 144.
Solution: By simple division, 8 \div 2 = 4
As per the multiplication table of 144,
= (8 \div 2) \times 144
= 4 \times 144
= 574
Thus the value of (8 \div 2) \times 144 is, 574
Problem 4: Find the value of 144 \times 7
Solution: From the table, 144 \times 7 = 1008
Problem 5: Find the value of 144 \times (5 - 3)
Solution: By simple subtraction, 5 - 3 = 2
From the table
= 144 \times (5 - 3)
= 144 \times 2
= 288
Thus the value of 144 \times (5 - 3) is, 288
The factors of 144 are 1,2,3,4,6,8,9,12,16,18,24,36,48,72,144 thus 144 has 15 factors.
No, 144 does not divide 1427 fully, thus 1427 is not divisible by 144.
There exist 3 prime factors of 144, which are 1,2,3.
A multiplication table is really helpful in real-life applications such as calculating area or counting multiple items of the same type, even counting the number of rows or columns in a particular table.
No it is not important to follow the order in multiplication, two or more numbers can be multiplied in any order and the final result will be the same.
