Given numbers are 217, 472, 905

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

Apply this formula for all numbers.

Step1:

LCM(217, 472) = 102424

GCD(217, 472) = ( 217 x 472 ) / 102424

= 217 / 472

= 217

Step2:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 217, 472, 905 is 1
