Given numbers are 258, 430, 819, 847

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 430 are 2 x 5 x 43

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

Prime factors of 847 are 7 x 11 x 11

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

Given numbers are 258, 430, 819, 847

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

Apply this formula for all numbers.

Step1:

LCM(258, 430) = 1290

GCD(258, 430) = ( 258 x 430 ) / 1290

= 258 / 430

= 258

Step2:

LCM(86, 819) = 70434

GCD(86, 819) = ( 86 x 819 ) / 70434

= 86 / 819

= 86

Step3:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

So, Greatest Common Divisor of 258, 430, 819, 847 is 1
