The list of prime factors of all numbers are
Prime factors of 651 are 3 x 7 x 31
Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 478 are 2 x 239
Prime factors of 766 are 2 x 383
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 651, 640, 478, 766
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 640) = 416640
GCD(651, 640) = ( 651 x 640 ) / 416640
= 651 / 640
= 651
Step2:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
Step3:
LCM(1, 766) = 766
GCD(1, 766) = ( 1 x 766 ) / 766
= 1 / 766
= 1
So, Greatest Common Divisor of 651, 640, 478, 766 is 1
