400000 in Words

Introduction

As you know, adding a zero after a number increases the value of the number by ten folds. This is because of place values. These place values not only help us in determining the value of the number but also in writing the number in word format. 400000 in words can be either four hundred thousand or four lakhs. Both are right. As per the international number system, 400000 in words is four hundred thousand, and as per the Indian number system, it is four lakhs. If we were to say that we bought a house that cost us 400000. We would say we bought a house for four lakhs or four hundred thousand rupees. Four lakh is an even number since it ends with a zero and is also a composite number.

400000 in Words Using a Place Value Chart

First, what are the place values? Place value is the value a digit holds based on where the digit is placed in the number.

Using this place value chart, let us first write 400000 in an expanded format.

\begin{aligned}

&=4 \times 100000+0 \times 10000+0 \times 1000+0 \times 100+0 \times 10+0 \times 1 \\

&=400000+0+0+0+0+0 \\

&=400000

\end{aligned}

And 400000 in words is four lakhs of four hundred thousand.

Even Numbers

Even numbers are numbers that are completely divisible by two. These numbers end with zero, two, four, six, or eight. So what does this say about four lakhs? Four lakhs ends with a zero, and it is completely divisible by two hence, it is an even number.

Odd Numbers

Odd numbers are numbers that are not completely divisible by two. They give a decimal answer when they are divided by two. These numbers end with one, three, five, seven, or nine. We already know four lakh is an even number, so we automatically know it is not an odd number.

Prime Numbers

Prime numbers are only completely divisible by two numbers; one and the number itself. Two, three, five, seven, etc., are all examples of prime numbers. Two is the only even prime number, and it is also the smallest prime number. If two is the only even prime number and four lakh is an even number, we automatically know that four lakh cannot be a prime number.

Composite Numbers

A composite number is a natural number completely divisible by more than 2 numbers. All natural numbers except for prime numbers are composite numbers. Four, six, eight, ten, etc., are all composite numbers. We said earlier that four lakh is not a prime number; therefore, it is a composite number.

Examples

What is the answer to five thousand added to four lakhs?

Four lakhs plus five thousand is equal to four lakh five thousand

400000+5000=405000

Another example is to imagine we are writing a cheque for 400000 rupees. We would write four lakh rupees in the cheque or four hundred thousand rupees. Rupees is the currency of India. What would it be in America? It would be four hundred thousand dollars. In Russia? Four hundred thousand Russian rubles.
