Steps to Calculate GCD of 403, 169, 326, 821 using LCM Formula
Given numbers are 403, 169, 326, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 169) = 5239
GCD(403, 169) = ( 403 x 169 ) / 5239
= 403 / 169
= 403
Step2:
LCM(13, 326) = 4238
GCD(13, 326) = ( 13 x 326 ) / 4238
= 13 / 326
= 13
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 403, 169, 326, 821 is 1
