Steps to Calculate GCD of 561, 153, 111, 559 using LCM Formula
Given numbers are 561, 153, 111, 559
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 153) = 1683
GCD(561, 153) = ( 561 x 153 ) / 1683
= 561 / 153
= 561
Step2:
LCM(51, 111) = 1887
GCD(51, 111) = ( 51 x 111 ) / 1887
= 51 / 111
= 51
Step3:
LCM(3, 559) = 1677
GCD(3, 559) = ( 3 x 559 ) / 1677
= 3 / 559
= 3
So, Greatest Common Divisor of 561, 153, 111, 559 is 1
