Steps to Calculate GCD of 123, 308, 809, 154 using LCM Formula
Given numbers are 123, 308, 809, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 308) = 37884
GCD(123, 308) = ( 123 x 308 ) / 37884
= 123 / 308
= 123
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 123, 308, 809, 154 is 1
