Steps to Calculate GCD of 208, 403, 210, 503 using LCM Formula

Given numbers are 208, 403, 210, 503

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

Apply this formula for all numbers.

Step1:

LCM(208, 403) = 6448

GCD(208, 403) = ( 208 x 403 ) / 6448

= 208 / 403

= 208


Step2:

LCM(13, 210) = 2730

GCD(13, 210) = ( 13 x 210 ) / 2730

= 13 / 210

= 13


Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1


So, Greatest Common Divisor of 208, 403, 210, 503 is 1
