Given numbers are 258, 780, 851, 449

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 851 are 23 x 37

Prime factors of 449 are 449

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

Given numbers are 258, 780, 851, 449

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

Apply this formula for all numbers.

Step1:

LCM(258, 780) = 33540

GCD(258, 780) = ( 258 x 780 ) / 33540

= 258 / 780

= 258

Step2:

LCM(6, 851) = 5106

GCD(6, 851) = ( 6 x 851 ) / 5106

= 6 / 851

= 6

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 258, 780, 851, 449 is 1
