Given numbers are 654, 572, 85, 686

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 572 are 2 x 2 x 11 x 13

Prime factors of 85 are 5 x 17

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 654, 572, 85, 686

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

Apply this formula for all numbers.

Step1:

LCM(654, 572) = 187044

GCD(654, 572) = ( 654 x 572 ) / 187044

= 654 / 572

= 654

Step2:

LCM(2, 85) = 170

GCD(2, 85) = ( 2 x 85 ) / 170

= 2 / 85

= 2

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 654, 572, 85, 686 is 1
