GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(118, 470) = 27730
GCD(118, 470) = ( 118 x 470 ) / 27730
= 118 / 470
= 118
Step2:
LCM(2, 454) = 454
GCD(2, 454) = ( 2 x 454 ) / 454
= 2 / 454
= 2
Step3:
LCM(2, 642) = 642
GCD(2, 642) = ( 2 x 642 ) / 642
= 2 / 642
= 2
So, Greatest Common Divisor of 118, 470, 454, 642 is 2
