Given numbers are 637, 620, 15, 511

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

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

Prime factors of 15 are 3 x 5

Prime factors of 511 are 7 x 73

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

Given numbers are 637, 620, 15, 511

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

Apply this formula for all numbers.

Step1:

LCM(637, 620) = 394940

GCD(637, 620) = ( 637 x 620 ) / 394940

= 637 / 620

= 637

Step2:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 637, 620, 15, 511 is 1
