GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(746, 642) = 239466
GCD(746, 642) = ( 746 x 642 ) / 239466
= 746 / 642
= 746
Step2:
LCM(2, 146) = 146
GCD(2, 146) = ( 2 x 146 ) / 146
= 2 / 146
= 2
Step3:
LCM(2, 456) = 456
GCD(2, 456) = ( 2 x 456 ) / 456
= 2 / 456
= 2
So, Greatest Common Divisor of 746, 642, 146, 456 is 2
