Steps to Calculate GCD of 438, 199, 323, 428 using LCM Formula

Given numbers are 438, 199, 323, 428

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

Apply this formula for all numbers.

Step1:

LCM(438, 199) = 87162

GCD(438, 199) = ( 438 x 199 ) / 87162

= 438 / 199

= 438


Step2:

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

= 1 / 323

= 1


Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1


So, Greatest Common Divisor of 438, 199, 323, 428 is 1
