Steps to Calculate GCD of 678, 889, 831, 123 using LCM Formula
Given numbers are 678, 889, 831, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 889) = 602742
GCD(678, 889) = ( 678 x 889 ) / 602742
= 678 / 889
= 678
Step2:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 678, 889, 831, 123 is 1
