GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(474, 638) = 151206
GCD(474, 638) = ( 474 x 638 ) / 151206
= 474 / 638
= 474
Step2:
LCM(2, 102) = 102
GCD(2, 102) = ( 2 x 102 ) / 102
= 2 / 102
= 2
Step3:
LCM(2, 798) = 798
GCD(2, 798) = ( 2 x 798 ) / 798
= 2 / 798
= 2
So, Greatest Common Divisor of 474, 638, 102, 798 is 2
