Given numbers are 715, 321, 172

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

Apply this formula for all numbers.

Step1:

LCM(715, 321) = 229515

GCD(715, 321) = ( 715 x 321 ) / 229515

= 715 / 321

= 715

Step2:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 715, 321, 172 is 1
