Given numbers are 175, 861, 770, 640

The list of prime factors of all numbers are

Prime factors of 175 are 5 x 5 x 7

Prime factors of 861 are 3 x 7 x 41

Prime factors of 770 are 2 x 5 x 7 x 11

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

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

Given numbers are 175, 861, 770, 640

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

Apply this formula for all numbers.

Step1:

LCM(175, 861) = 21525

GCD(175, 861) = ( 175 x 861 ) / 21525

= 175 / 861

= 175

Step2:

LCM(7, 770) = 770

GCD(7, 770) = ( 7 x 770 ) / 770

= 7 / 770

= 7

Step3:

LCM(7, 640) = 4480

GCD(7, 640) = ( 7 x 640 ) / 4480

= 7 / 640

= 7

So, Greatest Common Divisor of 175, 861, 770, 640 is 1
