Question

Which choice is not a factor of 30? 12,3,2,5

Answer 1

First option : 12 is not a factor of 30

Step-by-step explanation:

We are asked to find if the given choices are a factor of 30 or not.

There are two methods to check whether a number is factor of another or not.

1. First states that we should find the factors of the number and then check if the given number exists in the factors or not.

2. we can divide the number by factor, if the division is complete without any remainder, then the divisor is a factor.

So,

for 12, we will divide 30 by 12

=$\frac{30}{12} = 2.5$

The quotient should be a whole number in order for 12 to be factor of 30. as the quotient is not a whole number, 12 is not a factor of 30
