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

Apply this formula for all numbers.

Step1:

LCM(138, 921) = 42366

GCD(138, 921) = ( 138 x 921 ) / 42366

= 138 / 921

= 138

Step2:

LCM(3, 450) = 450

GCD(3, 450) = ( 3 x 450 ) / 450

= 3 / 450

= 3

So, Greatest Common Divisor of 138, 921, 450 is 3
