GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(450, 648) = 16200
GCD(450, 648) = ( 450 x 648 ) / 16200
= 450 / 648
= 450
Step2:
LCM(18, 778) = 7002
GCD(18, 778) = ( 18 x 778 ) / 7002
= 18 / 778
= 18
Step3:
LCM(2, 418) = 418
GCD(2, 418) = ( 2 x 418 ) / 418
= 2 / 418
= 2
So, Greatest Common Divisor of 450, 648, 778, 418 is 2
