Given numbers are 144, 570, 175, 391

The list of prime factors of all numbers are

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

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 175 are 5 x 5 x 7

Prime factors of 391 are 17 x 23

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

Given numbers are 144, 570, 175, 391

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

Apply this formula for all numbers.

Step1:

LCM(144, 570) = 13680

GCD(144, 570) = ( 144 x 570 ) / 13680

= 144 / 570

= 144

Step2:

LCM(6, 175) = 1050

GCD(6, 175) = ( 6 x 175 ) / 1050

= 6 / 175

= 6

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 144, 570, 175, 391 is 1
