Steps to Calculate GCD of 405, 403, 68, 193 using LCM Formula
Given numbers are 405, 403, 68, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 403) = 163215
GCD(405, 403) = ( 405 x 403 ) / 163215
= 405 / 403
= 405
Step2:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 405, 403, 68, 193 is 1
