GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 109) = 49813
GCD(457, 109) = ( 457 x 109 ) / 49813
= 457 / 109
= 457
Step2:
LCM(1, 743) = 743
GCD(1, 743) = ( 1 x 743 ) / 743
= 1 / 743
= 1
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 457, 109, 743, 128 is 1
