Steps to Calculate GCD of 649, 789, 128, 609 using LCM Formula
Given numbers are 649, 789, 128, 609
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 789) = 512061
GCD(649, 789) = ( 649 x 789 ) / 512061
= 649 / 789
= 649
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
So, Greatest Common Divisor of 649, 789, 128, 609 is 1
