Given numbers are 617, 504, 391, 392

The list of prime factors of all numbers are

Prime factors of 617 are 617

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 391 are 17 x 23

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 617, 504, 391, 392

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

Apply this formula for all numbers.

Step1:

LCM(617, 504) = 310968

GCD(617, 504) = ( 617 x 504 ) / 310968

= 617 / 504

= 617

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 617, 504, 391, 392 is 1
