Steps to Calculate GCD of 961, 643, 113, 385 using LCM Formula
Given numbers are 961, 643, 113, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(961, 643) = 617923
GCD(961, 643) = ( 961 x 643 ) / 617923
= 961 / 643
= 961
Step2:
LCM(1, 113) = 113
GCD(1, 113) = ( 1 x 113 ) / 113
= 1 / 113
= 1
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 961, 643, 113, 385 is 1
