Given numbers are 684, 621, 986, 645

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Prime factors of 986 are 2 x 17 x 29

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 684, 621, 986, 645

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

Apply this formula for all numbers.

Step1:

LCM(684, 621) = 47196

GCD(684, 621) = ( 684 x 621 ) / 47196

= 684 / 621

= 684

Step2:

LCM(9, 986) = 8874

GCD(9, 986) = ( 9 x 986 ) / 8874

= 9 / 986

= 9

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 684, 621, 986, 645 is 1
