Steps to Calculate GCD of 123, 553, 153, 551 using LCM Formula
Given numbers are 123, 553, 153, 551
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 553) = 68019
GCD(123, 553) = ( 123 x 553 ) / 68019
= 123 / 553
= 123
Step2:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
Step3:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
So, Greatest Common Divisor of 123, 553, 153, 551 is 1
