What is the highest common factor of 350?

Answer 1

There's no such thing as a common factor of one number. The word "common" means "same for both".

You need at least two numbers, in order to find a factor that's "common" to both of them.

Answer 2

The highest common factor of 350 is 50. To find the highest common factor, you need to factorize the number 350 into its prime factors, which are 2 x 5^2 x 7. Then, you identify the common factors with the number 350, which are 2 x 5^2 = 50. This is the highest common factor of 350.
