Steps to Calculate GCD of 199, 645, 731, 243 using LCM Formula

Given numbers are 199, 645, 731, 243

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(199, 645) = 128355

GCD(199, 645) = ( 199 x 645 ) / 128355

= 199 / 645

= 199


Step2:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1


Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1


So, Greatest Common Divisor of 199, 645, 731, 243 is 1
