GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(622, 220) = 68420
GCD(622, 220) = ( 622 x 220 ) / 68420
= 622 / 220
= 622
Step2:
LCM(2, 972) = 972
GCD(2, 972) = ( 2 x 972 ) / 972
= 2 / 972
= 2
Step3:
LCM(2, 256) = 256
GCD(2, 256) = ( 2 x 256 ) / 256
= 2 / 256
= 2
So, Greatest Common Divisor of 622, 220, 972, 256 is 2
