Given numbers are 621, 718, 909, 672

The list of prime factors of all numbers are

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

Prime factors of 718 are 2 x 359

Prime factors of 909 are 3 x 3 x 101

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 621, 718, 909, 672

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

Apply this formula for all numbers.

Step1:

LCM(621, 718) = 445878

GCD(621, 718) = ( 621 x 718 ) / 445878

= 621 / 718

= 621

Step2:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 621, 718, 909, 672 is 1
