Steps to Calculate GCD of 840, 477, 401, 478 using LCM Formula

Given numbers are 840, 477, 401, 478

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

Apply this formula for all numbers.

Step1:

LCM(840, 477) = 133560

GCD(840, 477) = ( 840 x 477 ) / 133560

= 840 / 477

= 840


Step2:

LCM(3, 401) = 1203

GCD(3, 401) = ( 3 x 401 ) / 1203

= 3 / 401

= 3


Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1


So, Greatest Common Divisor of 840, 477, 401, 478 is 1
