Given numbers are 640, 401, 902, 175

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 401 are 401

Prime factors of 902 are 2 x 11 x 41

Prime factors of 175 are 5 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 640, 401, 902, 175

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(640, 401) = 256640

GCD(640, 401) = ( 640 x 401 ) / 256640

= 640 / 401

= 640

Step2:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

Step3:

LCM(1, 175) = 175

GCD(1, 175) = ( 1 x 175 ) / 175

= 1 / 175

= 1

So, Greatest Common Divisor of 640, 401, 902, 175 is 1
