Steps to Calculate GCD of 991, 390, 477, 224 using LCM Formula

Given numbers are 991, 390, 477, 224

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

Apply this formula for all numbers.

Step1:

LCM(991, 390) = 386490

GCD(991, 390) = ( 991 x 390 ) / 386490

= 991 / 390

= 991


Step2:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1


Step3:

LCM(1, 224) = 224

GCD(1, 224) = ( 1 x 224 ) / 224

= 1 / 224

= 1


So, Greatest Common Divisor of 991, 390, 477, 224 is 1
