Given numbers are 217, 478, 715

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

Apply this formula for all numbers.

Step1:

LCM(217, 478) = 103726

GCD(217, 478) = ( 217 x 478 ) / 103726

= 217 / 478

= 217

Step2:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 217, 478, 715 is 1
