Given numbers are 620, 318, 773, 637

The list of prime factors of all numbers are

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

Prime factors of 318 are 2 x 3 x 53

Prime factors of 773 are 773

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 620, 318, 773, 637

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

Apply this formula for all numbers.

Step1:

LCM(620, 318) = 98580

GCD(620, 318) = ( 620 x 318 ) / 98580

= 620 / 318

= 620

Step2:

LCM(2, 773) = 1546

GCD(2, 773) = ( 2 x 773 ) / 1546

= 2 / 773

= 2

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 620, 318, 773, 637 is 1
