Steps to Calculate GCD of 403, 276, 637, 378 using LCM Formula

Given numbers are 403, 276, 637, 378

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

Apply this formula for all numbers.

Step1:

LCM(403, 276) = 111228

GCD(403, 276) = ( 403 x 276 ) / 111228

= 403 / 276

= 403


Step2:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1


Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1


So, Greatest Common Divisor of 403, 276, 637, 378 is 1
