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

Apply this formula for all numbers.

Step1:

LCM(138, 846) = 19458

GCD(138, 846) = ( 138 x 846 ) / 19458

= 138 / 846

= 138

Step2:

LCM(6, 618) = 618

GCD(6, 618) = ( 6 x 618 ) / 618

= 6 / 618

= 6

Step3:

LCM(6, 128) = 384

GCD(6, 128) = ( 6 x 128 ) / 384

= 6 / 128

= 6

So, Greatest Common Divisor of 138, 846, 618, 128 is 2
