Given numbers are 245, 720, 479, 285

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

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

Prime factors of 479 are 479

Prime factors of 285 are 3 x 5 x 19

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

Given numbers are 245, 720, 479, 285

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

Apply this formula for all numbers.

Step1:

LCM(245, 720) = 35280

GCD(245, 720) = ( 245 x 720 ) / 35280

= 245 / 720

= 245

Step2:

LCM(5, 479) = 2395

GCD(5, 479) = ( 5 x 479 ) / 2395

= 5 / 479

= 5

Step3:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 245, 720, 479, 285 is 1
