Given numbers are 611, 639, 756, 388

The list of prime factors of all numbers are

Prime factors of 611 are 13 x 47

Prime factors of 639 are 3 x 3 x 71

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 611, 639, 756, 388

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

Apply this formula for all numbers.

Step1:

LCM(611, 639) = 390429

GCD(611, 639) = ( 611 x 639 ) / 390429

= 611 / 639

= 611

Step2:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 611, 639, 756, 388 is 1
