Given numbers are 375, 144, 173, 648

The list of prime factors of all numbers are

Prime factors of 375 are 3 x 5 x 5 x 5

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 173 are 173

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 375, 144, 173, 648

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

Apply this formula for all numbers.

Step1:

LCM(375, 144) = 18000

GCD(375, 144) = ( 375 x 144 ) / 18000

= 375 / 144

= 375

Step2:

LCM(3, 173) = 519

GCD(3, 173) = ( 3 x 173 ) / 519

= 3 / 173

= 3

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 375, 144, 173, 648 is 1
