Given numbers are 258, 454, 945, 432

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 454 are 2 x 227

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 258, 454, 945, 432

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

Apply this formula for all numbers.

Step1:

LCM(258, 454) = 58566

GCD(258, 454) = ( 258 x 454 ) / 58566

= 258 / 454

= 258

Step2:

LCM(2, 945) = 1890

GCD(2, 945) = ( 2 x 945 ) / 1890

= 2 / 945

= 2

Step3:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

So, Greatest Common Divisor of 258, 454, 945, 432 is 1
