Steps to Calculate GCD of 207, 309, 731, 664 using LCM Formula
Given numbers are 207, 309, 731, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 309) = 21321
GCD(207, 309) = ( 207 x 309 ) / 21321
= 207 / 309
= 207
Step2:
LCM(3, 731) = 2193
GCD(3, 731) = ( 3 x 731 ) / 2193
= 3 / 731
= 3
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 207, 309, 731, 664 is 1
