### Example: Find factors of 400 that add upto 42

• Sum of 2 and 40 : 2 + 40 = 42

Hence, factors of 400 that add upto 42 are 2 and 40.

#### Steps to find Factors of 400

• Step 1. Find all the numbers that would divide 400 without leaving any remainder. Starting with the number 1 upto 200 (half of 400). The number 1 and the number itself are always factors of the given number.
400 ÷ 1 : Remainder = 0
400 ÷ 2 : Remainder = 0
400 ÷ 4 : Remainder = 0
400 ÷ 5 : Remainder = 0
400 ÷ 8 : Remainder = 0
400 ÷ 10 : Remainder = 0
400 ÷ 16 : Remainder = 0
400 ÷ 20 : Remainder = 0
400 ÷ 25 : Remainder = 0
400 ÷ 40 : Remainder = 0
400 ÷ 50 : Remainder = 0
400 ÷ 80 : Remainder = 0
400 ÷ 100 : Remainder = 0
400 ÷ 200 : Remainder = 0
400 ÷ 400 : Remainder = 0

Hence, Factors of 400 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, and 400

#### What are factors?

In mathematics, the term factor is used for that number which divides the other number to leave 0 as a remainder. A factor of a number can be positive or negative.

#### Properties of Factors

• Factors and multiples are two different terms. Factors are those number which when multiplied together give the number itself, on the other hand multiples are what we get after multiplying the same number with and other number.
• Prime factors are those factors which are further divisible by only two numbers i.e. 1 ans the factor itself.
• Every number is a factor of zero (0), since 400 x 0 = 0.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Every factor of a number is an exact divisor of that number, example 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400 are exact divisors of 400.
