Given numbers are 173, 555, 860, 945

The list of prime factors of all numbers are

Prime factors of 173 are 173

Prime factors of 555 are 3 x 5 x 37

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 173, 555, 860, 945

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

Apply this formula for all numbers.

Step1:

LCM(173, 555) = 96015

GCD(173, 555) = ( 173 x 555 ) / 96015

= 173 / 555

= 173

Step2:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 173, 555, 860, 945 is 1
