Steps to Calculate GCD of 420, 497, 204, 723 using LCM Formula

Given numbers are 420, 497, 204, 723

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

Apply this formula for all numbers.

Step1:

LCM(420, 497) = 29820

GCD(420, 497) = ( 420 x 497 ) / 29820

= 420 / 497

= 420


Step2:

LCM(7, 204) = 1428

GCD(7, 204) = ( 7 x 204 ) / 1428

= 7 / 204

= 7


Step3:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1


So, Greatest Common Divisor of 420, 497, 204, 723 is 1
