Given numbers are 172, 217, 715

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

Apply this formula for all numbers.

Step1:

LCM(172, 217) = 37324

GCD(172, 217) = ( 172 x 217 ) / 37324

= 172 / 217

= 172

Step2:

LCM(1, 715) = 715

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

= 1 / 715

= 1

So, Greatest Common Divisor of 172, 217, 715 is 1
