Given numbers are 621, 794, 693, 636

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 794 are 2 x 397

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 621, 794, 693, 636

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

Apply this formula for all numbers.

Step1:

LCM(621, 794) = 493074

GCD(621, 794) = ( 621 x 794 ) / 493074

= 621 / 794

= 621

Step2:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 621, 794, 693, 636 is 1
