Steps to Calculate GCD of 123, 818, 105, 404 using LCM Formula
Given numbers are 123, 818, 105, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 818) = 100614
GCD(123, 818) = ( 123 x 818 ) / 100614
= 123 / 818
= 123
Step2:
LCM(1, 105) = 105
GCD(1, 105) = ( 1 x 105 ) / 105
= 1 / 105
= 1
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 123, 818, 105, 404 is 1
