Given numbers are 684, 620, 486, 679

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 620 are 2 x 2 x 5 x 31

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 679 are 7 x 97

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

Given numbers are 684, 620, 486, 679

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

Apply this formula for all numbers.

Step1:

LCM(684, 620) = 106020

GCD(684, 620) = ( 684 x 620 ) / 106020

= 684 / 620

= 684

Step2:

LCM(4, 486) = 972

GCD(4, 486) = ( 4 x 486 ) / 972

= 4 / 486

= 4

Step3:

LCM(2, 679) = 1358

GCD(2, 679) = ( 2 x 679 ) / 1358

= 2 / 679

= 2

So, Greatest Common Divisor of 684, 620, 486, 679 is 1
