Given numbers are 387, 634, 548, 657

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 634 are 2 x 317

Prime factors of 548 are 2 x 2 x 137

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 387, 634, 548, 657

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

Apply this formula for all numbers.

Step1:

LCM(387, 634) = 245358

GCD(387, 634) = ( 387 x 634 ) / 245358

= 387 / 634

= 387

Step2:

LCM(1, 548) = 548

GCD(1, 548) = ( 1 x 548 ) / 548

= 1 / 548

= 1

Step3:

LCM(1, 657) = 657

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

= 1 / 657

= 1

So, Greatest Common Divisor of 387, 634, 548, 657 is 1
