Steps to Calculate GCD of 641, 353, 87, 789 using LCM Formula
Given numbers are 641, 353, 87, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(641, 353) = 226273
GCD(641, 353) = ( 641 x 353 ) / 226273
= 641 / 353
= 641
Step2:
LCM(1, 87) = 87
GCD(1, 87) = ( 1 x 87 ) / 87
= 1 / 87
= 1
Step3:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 641, 353, 87, 789 is 1
