Question

Answer 1

Answer:

I think 4 is the common factor for 20,24&40

Answer 2

Answer: 4

Greatest Common Factor is also known as GCF or HCF

HCF of 20, 24 and 40:

First we need to state the factors of each of the numbers

20 = 2 x 2 x 5

24 = 2 x 2 x 2 x 3

40 = 2 x 2 x 2 x 5

So the HCF is the product of the common factors of the number

So here 2 x 2 is common in all three

So 2 x 2 = 4

So HCF = 4

Hope this was helpful and clear
