The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 289 are 17 x 17

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 445, 550, 289, 245

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

Apply this formula for all numbers.

Step1:

LCM(445, 550) = 48950

GCD(445, 550) = ( 445 x 550 ) / 48950

= 445 / 550

= 445

Step2:

LCM(5, 289) = 1445

GCD(5, 289) = ( 5 x 289 ) / 1445

= 5 / 289

= 5

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 445, 550, 289, 245 is 1
