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

Apply this formula for all numbers.

Step1:

LCM(657, 642) = 140598

GCD(657, 642) = ( 657 x 642 ) / 140598

= 657 / 642

= 657

Step2:

LCM(3, 159) = 159

GCD(3, 159) = ( 3 x 159 ) / 159

= 3 / 159

= 3

Step3:

LCM(3, 879) = 879

GCD(3, 879) = ( 3 x 879 ) / 879

= 3 / 879

= 3

So, Greatest Common Divisor of 657, 642, 159, 879 is 3
