Given numbers are 172, 712, 691

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

Apply this formula for all numbers.

Step1:

LCM(172, 712) = 30616

GCD(172, 712) = ( 172 x 712 ) / 30616

= 172 / 712

= 172

Step2:

LCM(4, 691) = 2764

GCD(4, 691) = ( 4 x 691 ) / 2764

= 4 / 691

= 4

So, Greatest Common Divisor of 172, 712, 691 is 1
