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

Apply this formula for all numbers.

Step1:

LCM(639, 876) = 186588

GCD(639, 876) = ( 639 x 876 ) / 186588

= 639 / 876

= 639

Step2:

LCM(3, 529) = 1587

GCD(3, 529) = ( 3 x 529 ) / 1587

= 3 / 529

= 3

Step3:

LCM(1, 686) = 686

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

= 1 / 686

= 1

So, Greatest Common Divisor of 639, 876, 529, 686 is 1
