Steps to Calculate GCD of 189, 116, 921, 655 using LCM Formula
Given numbers are 189, 116, 921, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 116) = 21924
GCD(189, 116) = ( 189 x 116 ) / 21924
= 189 / 116
= 189
Step2:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
Step3:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
So, Greatest Common Divisor of 189, 116, 921, 655 is 1
