Given numbers are 651, 720, 953, 770

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 953 are 953

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

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

Given numbers are 651, 720, 953, 770

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

Apply this formula for all numbers.

Step1:

LCM(651, 720) = 156240

GCD(651, 720) = ( 651 x 720 ) / 156240

= 651 / 720

= 651

Step2:

LCM(3, 953) = 2859

GCD(3, 953) = ( 3 x 953 ) / 2859

= 3 / 953

= 3

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 651, 720, 953, 770 is 1
