Steps to Calculate GCD of 218, 855, 792, 398 using LCM Formula

Given numbers are 218, 855, 792, 398

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

Apply this formula for all numbers.

Step1:

LCM(218, 855) = 186390

GCD(218, 855) = ( 218 x 855 ) / 186390

= 218 / 855

= 218


Step2:

LCM(1, 792) = 792

GCD(1, 792) = ( 1 x 792 ) / 792

= 1 / 792

= 1


Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1


So, Greatest Common Divisor of 218, 855, 792, 398 is 1
