Given numbers are 255, 245, 278

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 245 are 5 x 7 x 7

Prime factors of 278 are 2 x 139

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

Given numbers are 255, 245, 278

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

Apply this formula for all numbers.

Step1:

LCM(255, 245) = 12495

GCD(255, 245) = ( 255 x 245 ) / 12495

= 255 / 245

= 255

Step2:

LCM(5, 278) = 1390

GCD(5, 278) = ( 5 x 278 ) / 1390

= 5 / 278

= 5

So, Greatest Common Divisor of 255, 245, 278 is 1
