Steps to Calculate GCD of 813, 163, 667, 821 using LCM Formula
Given numbers are 813, 163, 667, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 163) = 132519
GCD(813, 163) = ( 813 x 163 ) / 132519
= 813 / 163
= 813
Step2:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 813, 163, 667, 821 is 1
