Given numbers are 137, 620, 485, 756

The list of prime factors of all numbers are

Prime factors of 137 are 137

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 485 are 5 x 97

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

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

Given numbers are 137, 620, 485, 756

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

Apply this formula for all numbers.

Step1:

LCM(137, 620) = 84940

GCD(137, 620) = ( 137 x 620 ) / 84940

= 137 / 620

= 137

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

Step3:

LCM(1, 756) = 756

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

= 1 / 756

= 1

So, Greatest Common Divisor of 137, 620, 485, 756 is 1
