Given numbers are 388, 616, 687, 492

The list of prime factors of all numbers are

Prime factors of 388 are 2 x 2 x 97

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

Prime factors of 687 are 3 x 229

Prime factors of 492 are 2 x 2 x 3 x 41

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

Given numbers are 388, 616, 687, 492

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

Apply this formula for all numbers.

Step1:

LCM(388, 616) = 59752

GCD(388, 616) = ( 388 x 616 ) / 59752

= 388 / 616

= 388

Step2:

LCM(4, 687) = 2748

GCD(4, 687) = ( 4 x 687 ) / 2748

= 4 / 687

= 4

Step3:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

So, Greatest Common Divisor of 388, 616, 687, 492 is 1
