Given numbers are 680, 454, 635, 657

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 454 are 2 x 227

Prime factors of 635 are 5 x 127

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 680, 454, 635, 657

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

Apply this formula for all numbers.

Step1:

LCM(680, 454) = 154360

GCD(680, 454) = ( 680 x 454 ) / 154360

= 680 / 454

= 680

Step2:

LCM(2, 635) = 1270

GCD(2, 635) = ( 2 x 635 ) / 1270

= 2 / 635

= 2

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 680, 454, 635, 657 is 1
