Given numbers are 642, 108, 879, 554

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

Apply this formula for all numbers.

Step1:

LCM(642, 108) = 11556

GCD(642, 108) = ( 642 x 108 ) / 11556

= 642 / 108

= 642

Step2:

LCM(6, 879) = 1758

GCD(6, 879) = ( 6 x 879 ) / 1758

= 6 / 879

= 6

Step3:

LCM(3, 554) = 1662

GCD(3, 554) = ( 3 x 554 ) / 1662

= 3 / 554

= 3

So, Greatest Common Divisor of 642, 108, 879, 554 is 1
