Given numbers are 285, 457, 338, 248

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 457 are 457

Prime factors of 338 are 2 x 13 x 13

Prime factors of 248 are 2 x 2 x 2 x 31

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

Given numbers are 285, 457, 338, 248

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

Apply this formula for all numbers.

Step1:

LCM(285, 457) = 130245

GCD(285, 457) = ( 285 x 457 ) / 130245

= 285 / 457

= 285

Step2:

LCM(1, 338) = 338

GCD(1, 338) = ( 1 x 338 ) / 338

= 1 / 338

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 285, 457, 338, 248 is 1
