Given numbers are 654, 172, 168, 865

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 172 are 2 x 2 x 43

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 865 are 5 x 173

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

Given numbers are 654, 172, 168, 865

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

Apply this formula for all numbers.

Step1:

LCM(654, 172) = 56244

GCD(654, 172) = ( 654 x 172 ) / 56244

= 654 / 172

= 654

Step2:

LCM(2, 168) = 168

GCD(2, 168) = ( 2 x 168 ) / 168

= 2 / 168

= 2

Step3:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

So, Greatest Common Divisor of 654, 172, 168, 865 is 1
