Question

Choose the correct option.

• A. 1 is not a factor of a number.
• B. 1 is a multiple of a number.
• C. The number itself is a multiple of the same number.
• D. The number itself cannot be a factor of the same number.

Answer 1

The correct option is C The number itself is a multiple of the same number.

The number itself is a factor and multiple of the same number.

For example, factors of 4 are 1, 2, 4

1 $\times$ 4 = 4
2 $\times$ 2 = 4

Hence, 4 is a factor of 4.

Multiples of 4 are 4, 8, 12, 16 and so on.

4 $\times$ 1 = 4
4 $\times$ 2 = 8
4 $\times$ 3 = 12
4 $\times$ 4 = 16

Here we observe that 4 is itself a multiple of 4.

Let's list the factors of 6.

1, 2, 3, 6

Here also we observe that 1 is a factor.

Hence, 1 is always a factor of any number.
