GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 558) = 178002
GCD(638, 558) = ( 638 x 558 ) / 178002
= 638 / 558
= 638
Step2:
LCM(2, 648) = 648
GCD(2, 648) = ( 2 x 648 ) / 648
= 2 / 648
= 2
Step3:
LCM(2, 983) = 1966
GCD(2, 983) = ( 2 x 983 ) / 1966
= 2 / 983
= 2
So, Greatest Common Divisor of 638, 558, 648, 983 is 1
