Given numbers are 627, 100, 468, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(627, 100) = 62700
GCD(627, 100) = ( 627 x 100 ) / 62700
= 627 / 100
= 627
Step2:
LCM(1, 468) = 468
GCD(1, 468) = ( 1 x 468 ) / 468
= 1 / 468
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 627, 100, 468, 420 is 1
