Steps to Calculate GCD of 643, 451, 789, 331 using LCM Formula
Given numbers are 643, 451, 789, 331
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 451) = 289993
GCD(643, 451) = ( 643 x 451 ) / 289993
= 643 / 451
= 643
Step2:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
Step3:
LCM(1, 331) = 331
GCD(1, 331) = ( 1 x 331 ) / 331
= 1 / 331
= 1
So, Greatest Common Divisor of 643, 451, 789, 331 is 1
