Question

What are all the factors of 140

Answer 1

The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, and 140. These are all the numbers that can divide 140 without leaving a remainder.

Step-by-step explanation:

The question asks for all the factors of 140.

To find the factors of a number, you need to find all whole numbers that can divide 140 without leaving a remainder. These numbers are what we call factors.

The factors of 140 can be discovered through a process known as prime factorization or by systematically trying to divide 140 by integers.

Let's start with the number 1, which is a factor of every number. Then, we divide 140 by other integers to find additional factors.

1. 140 ÷ 1 = 140, so 1 and 140 are factors.
2. 140 ÷ 2 = 70, so 2 and 70 are factors.
3. 140 ÷ 4 = 35, so 4 and 35 are factors.
4. 140 ÷ 5 = 28, so 5 and 28 are factors.
5. 140 ÷ 7 = 20, so 7 and 20 are factors.
6. 140 ÷ 10 = 14, so 10 and 14 are factors.

The complete list of factors for the number 140 is therefore: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, and 140.
