Answer:
1, 2, 4, 5, 8, 10, 20, and 40
Step-by-step explanation:
To find the factors (the numbers that when multiplied together equate to the desired number) of 40, we think of the whole integers that can divide evenly into it, meaning when they divide into 40 the resulting quotient is another whole integer.
1 can divide evenly into 40, as 40 ÷ 1 = 40
2 can divide evenly into 40, as 40 ÷ 2 = 20
4 can divide evenly into 40 as 40 ÷ 4 = 10
5 can divide evenly into 40 as 40 ÷ 5 = 8
These numbers all become the factors.
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40
