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

Apply this formula for all numbers.

Step1:

LCM(638, 902) = 26158

GCD(638, 902) = ( 638 x 902 ) / 26158

= 638 / 902

= 638

Step2:

LCM(22, 154) = 154

GCD(22, 154) = ( 22 x 154 ) / 154

= 22 / 154

= 22

So, Greatest Common Divisor of 638, 902, 154 is 22
