Steps to Calculate GCD of 787, 113, 243, 155 using LCM Formula
Given numbers are 787, 113, 243, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 113) = 88931
GCD(787, 113) = ( 787 x 113 ) / 88931
= 787 / 113
= 787
Step2:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 787, 113, 243, 155 is 1
