Given numbers are 387, 616, 291, 656

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 291 are 3 x 97

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 387, 616, 291, 656

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

Apply this formula for all numbers.

Step1:

LCM(387, 616) = 238392

GCD(387, 616) = ( 387 x 616 ) / 238392

= 387 / 616

= 387

Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 387, 616, 291, 656 is 1
