Steps to Calculate GCD of 393, 367, 563, 645 using LCM Formula
Given numbers are 393, 367, 563, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 367) = 144231
GCD(393, 367) = ( 393 x 367 ) / 144231
= 393 / 367
= 393
Step2:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 393, 367, 563, 645 is 1
