Steps to Calculate GCD of 123, 219, 15, 496 using LCM Formula

Given numbers are 123, 219, 15, 496

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

Apply this formula for all numbers.

Step1:

LCM(123, 219) = 8979

GCD(123, 219) = ( 123 x 219 ) / 8979

= 123 / 219

= 123


Step2:

LCM(3, 15) = 15

GCD(3, 15) = ( 3 x 15 ) / 15

= 3 / 15

= 3


Step3:

LCM(3, 496) = 1488

GCD(3, 496) = ( 3 x 496 ) / 1488

= 3 / 496

= 3
