Given numbers are 621, 447, 992, 680

The list of prime factors of all numbers are

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

Prime factors of 447 are 3 x 149

Prime factors of 992 are 2 x 2 x 2 x 2 x 2 x 31

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 621, 447, 992, 680

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

Apply this formula for all numbers.

Step1:

LCM(621, 447) = 92529

GCD(621, 447) = ( 621 x 447 ) / 92529

= 621 / 447

= 621

Step2:

LCM(3, 992) = 2976

GCD(3, 992) = ( 3 x 992 ) / 2976

= 3 / 992

= 3

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 621, 447, 992, 680 is 1
