Given numbers are 172, 656, 647

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

Apply this formula for all numbers.

Step1:

LCM(172, 656) = 28208

GCD(172, 656) = ( 172 x 656 ) / 28208

= 172 / 656

= 172

Step2:

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

= 4 / 647

= 4

So, Greatest Common Divisor of 172, 656, 647 is 1
