Given numbers are 258, 308, 400, 669

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 669 are 3 x 223

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

Given numbers are 258, 308, 400, 669

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

Apply this formula for all numbers.

Step1:

LCM(258, 308) = 39732

GCD(258, 308) = ( 258 x 308 ) / 39732

= 258 / 308

= 258

Step2:

LCM(2, 400) = 400

GCD(2, 400) = ( 2 x 400 ) / 400

= 2 / 400

= 2

Step3:

LCM(2, 669) = 1338

GCD(2, 669) = ( 2 x 669 ) / 1338

= 2 / 669

= 2

So, Greatest Common Divisor of 258, 308, 400, 669 is 1
