Given numbers are 279, 138, 485

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

Apply this formula for all numbers.

Step1:

LCM(279, 138) = 12834

GCD(279, 138) = ( 279 x 138 ) / 12834

= 279 / 138

= 279

Step2:

LCM(3, 485) = 1455

GCD(3, 485) = ( 3 x 485 ) / 1455

= 3 / 485

= 3

So, Greatest Common Divisor of 279, 138, 485 is 1
