Given numbers are 621, 699, 427, 912

The list of prime factors of all numbers are

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

Prime factors of 699 are 3 x 233

Prime factors of 427 are 7 x 61

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

Given numbers are 621, 699, 427, 912

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

Apply this formula for all numbers.

Step1:

LCM(621, 699) = 144693

GCD(621, 699) = ( 621 x 699 ) / 144693

= 621 / 699

= 621

Step2:

LCM(3, 427) = 1281

GCD(3, 427) = ( 3 x 427 ) / 1281

= 3 / 427

= 3

Step3:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 621, 699, 427, 912 is 1
