Given numbers are 257, 447, 260, 913

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 447 are 3 x 149

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 913 are 11 x 83

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

Given numbers are 257, 447, 260, 913

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

Apply this formula for all numbers.

Step1:

LCM(257, 447) = 114879

GCD(257, 447) = ( 257 x 447 ) / 114879

= 257 / 447

= 257

Step2:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

Step3:

LCM(1, 913) = 913

GCD(1, 913) = ( 1 x 913 ) / 913

= 1 / 913

= 1

So, Greatest Common Divisor of 257, 447, 260, 913 is 1
