Given numbers are 138, 852, 650, 668

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

Apply this formula for all numbers.

Step1:

LCM(138, 852) = 19596

GCD(138, 852) = ( 138 x 852 ) / 19596

= 138 / 852

= 138

Step2:

LCM(6, 650) = 1950

GCD(6, 650) = ( 6 x 650 ) / 1950

= 6 / 650

= 6

Step3:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

So, Greatest Common Divisor of 138, 852, 650, 668 is 2
