GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(122, 312) = 19032
GCD(122, 312) = ( 122 x 312 ) / 19032
= 122 / 312
= 122
Step2:
LCM(2, 912) = 912
GCD(2, 912) = ( 2 x 912 ) / 912
= 2 / 912
= 2
Step3:
LCM(2, 644) = 644
GCD(2, 644) = ( 2 x 644 ) / 644
= 2 / 644
= 2
So, Greatest Common Divisor of 122, 312, 912, 644 is 2
