Given numbers are 483, 455, 208, 257

The list of prime factors of all numbers are

Prime factors of 483 are 3 x 7 x 23

Prime factors of 455 are 5 x 7 x 13

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 257 are 257

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

Given numbers are 483, 455, 208, 257

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

Apply this formula for all numbers.

Step1:

LCM(483, 455) = 31395

GCD(483, 455) = ( 483 x 455 ) / 31395

= 483 / 455

= 483

Step2:

LCM(7, 208) = 1456

GCD(7, 208) = ( 7 x 208 ) / 1456

= 7 / 208

= 7

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 483, 455, 208, 257 is 1
