Steps to Calculate GCD of 123, 721, 549, 845 using LCM Formula
Given numbers are 123, 721, 549, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 721) = 88683
GCD(123, 721) = ( 123 x 721 ) / 88683
= 123 / 721
= 123
Step2:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 123, 721, 549, 845 is 1
