Steps to Calculate GCD of 420, 400, 237 using LCM Formula

Given numbers are 420, 400, 237

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

Apply this formula for all numbers.

Step1:

LCM(420, 400) = 8400

GCD(420, 400) = ( 420 x 400 ) / 8400

= 420 / 400

= 420


Step2:

LCM(20, 237) = 4740

GCD(20, 237) = ( 20 x 237 ) / 4740

= 20 / 237

= 20


So, Greatest Common Divisor of 420, 400, 237 is 1
