About the number 72

72 is a natural number that is subsequent to the number 71 and prior to the number 73. In mathematics, natural numbers are positive integers that are used for counting purposes and are hence also referred to as counting numbers. Natural numbers start from 1 and go on till infinity. Thus the sequence of natural numbers is 1, 2, 3, 4,.... till infinity. As 72 falls within this sequence, it is considered a natural number.

72 is not an odd number. 72 is an even number as it can be divided by 2 to yield two equal parts. When 72 is divided by 2, the remainder is zero and thus it is an even number. Even numbers can be of one or more digits. Examples of one-digit even numbers are 0, 2, 4, 6, and 8. Examples of two-digit even numbers are 12, 14, 16,..., and so on till 98. A simple way of understanding if any number is even, is by checking if the last digit of the number is an even number. In 72, we see that the last digit is 2, which is indeed an even single-digit number. Hence we can easily determine that 72 is also an even number.

Divisibility status of 72

The number 72 is a composite number. A number is referred to as a composite number if it is divisible by any other number apart from 1 and the number itself. A composite number hence has more than two factors. For the number 72, we see that it is divisible by 1, 2, 3, 4, 8, 9, 12, 18, 24, 36, and 72. It has 11 factors and is hence a composite number. To find out if any number is divisible by another number, we need to follow a set of rules called divisibility rules. For example, the divisibility rule to check if a number is divisible by 2 is by confirming that the number is even. Similarly, there are such divisibility rules for all numbers.

Place value chart of 72
