Given numbers are 720, 171, 102, 445

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 171 are 3 x 3 x 19

Prime factors of 102 are 2 x 3 x 17

Prime factors of 445 are 5 x 89

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

Given numbers are 720, 171, 102, 445

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

Apply this formula for all numbers.

Step1:

LCM(720, 171) = 13680

GCD(720, 171) = ( 720 x 171 ) / 13680

= 720 / 171

= 720

Step2:

LCM(9, 102) = 306

GCD(9, 102) = ( 9 x 102 ) / 306

= 9 / 102

= 9

Step3:

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

= 3 / 445

= 3

So, Greatest Common Divisor of 720, 171, 102, 445 is 1
