Given numbers are 258, 210, 819, 770

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 258, 210, 819, 770

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

Apply this formula for all numbers.

Step1:

LCM(258, 210) = 9030

GCD(258, 210) = ( 258 x 210 ) / 9030

= 258 / 210

= 258

Step2:

LCM(6, 819) = 1638

GCD(6, 819) = ( 6 x 819 ) / 1638

= 6 / 819

= 6

Step3:

LCM(3, 770) = 2310

GCD(3, 770) = ( 3 x 770 ) / 2310

= 3 / 770

= 3

So, Greatest Common Divisor of 258, 210, 819, 770 is 1
