Given numbers are 285, 505, 19

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

Apply this formula for all numbers.

Step1:

LCM(285, 505) = 28785

GCD(285, 505) = ( 285 x 505 ) / 28785

= 285 / 505

= 285

Step2:

LCM(5, 19) = 95

GCD(5, 19) = ( 5 x 19 ) / 95

= 5 / 19

= 5

So, Greatest Common Divisor of 285, 505, 19 is 1
