Given numbers are 633, 556, 640, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(633, 556) = 351948
GCD(633, 556) = ( 633 x 556 ) / 351948
= 633 / 556
= 633
Step2:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
Step3:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
So, Greatest Common Divisor of 633, 556, 640, 427 is 1
