Given numbers are 656, 126, 903, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 126) = 41328
GCD(656, 126) = ( 656 x 126 ) / 41328
= 656 / 126
= 656
Step2:
LCM(2, 903) = 1806
GCD(2, 903) = ( 2 x 903 ) / 1806
= 2 / 903
= 2
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 656, 126, 903, 456 is 1
