Steps to Calculate GCD of 121, 194, 605, 991 using LCM Formula
Given numbers are 121, 194, 605, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(121, 194) = 23474
GCD(121, 194) = ( 121 x 194 ) / 23474
= 121 / 194
= 121
Step2:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 121, 194, 605, 991 is 1
