Given numbers are 245, 265, 280, 272

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 265 are 5 x 53

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

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

Given numbers are 245, 265, 280, 272

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

Apply this formula for all numbers.

Step1:

LCM(245, 265) = 12985

GCD(245, 265) = ( 245 x 265 ) / 12985

= 245 / 265

= 245

Step2:

LCM(5, 280) = 280

GCD(5, 280) = ( 5 x 280 ) / 280

= 5 / 280

= 5

Step3:

LCM(5, 272) = 1360

GCD(5, 272) = ( 5 x 272 ) / 1360

= 5 / 272

= 5

So, Greatest Common Divisor of 245, 265, 280, 272 is 1
