Given numbers are 258, 630, 388, 827

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 388 are 2 x 2 x 97

Prime factors of 827 are 827

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

Given numbers are 258, 630, 388, 827

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

Apply this formula for all numbers.

Step1:

LCM(258, 630) = 27090

GCD(258, 630) = ( 258 x 630 ) / 27090

= 258 / 630

= 258

Step2:

LCM(6, 388) = 1164

GCD(6, 388) = ( 6 x 388 ) / 1164

= 6 / 388

= 6

Step3:

LCM(2, 827) = 1654

GCD(2, 827) = ( 2 x 827 ) / 1654

= 2 / 827

= 2

So, Greatest Common Divisor of 258, 630, 388, 827 is 1
