Steps to Calculate GCD of 393, 201, 764, 665 using LCM Formula
Given numbers are 393, 201, 764, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 201) = 26331
GCD(393, 201) = ( 393 x 201 ) / 26331
= 393 / 201
= 393
Step2:
LCM(3, 764) = 2292
GCD(3, 764) = ( 3 x 764 ) / 2292
= 3 / 764
= 3
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 393, 201, 764, 665 is 1
