Given numbers are 652, 657, 917, 780

The list of prime factors of all numbers are

Prime factors of 652 are 2 x 2 x 163

Prime factors of 657 are 3 x 3 x 73

Prime factors of 917 are 7 x 131

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 652, 657, 917, 780

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

Apply this formula for all numbers.

Step1:

LCM(652, 657) = 428364

GCD(652, 657) = ( 652 x 657 ) / 428364

= 652 / 657

= 652

Step2:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 652, 657, 917, 780 is 1
