Steps to Calculate GCD of 991, 111, 427, 915 using LCM Formula
Given numbers are 991, 111, 427, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 111) = 110001
GCD(991, 111) = ( 991 x 111 ) / 110001
= 991 / 111
= 991
Step2:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 991, 111, 427, 915 is 1
