Given numbers are 130, 487, 172

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 487 are 487

Prime factors of 172 are 2 x 2 x 43

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 130, 487, 172

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

Apply this formula for all numbers.

Step1:

LCM(130, 487) = 63310

GCD(130, 487) = ( 130 x 487 ) / 63310

= 130 / 487

= 130

Step2:

LCM(1, 172) = 172

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

= 1 / 172

= 1

So, Greatest Common Divisor of 130, 487, 172 is 1
