Given numbers are 618, 864, 25, 605

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 25 are 5 x 5

Prime factors of 605 are 5 x 11 x 11

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

Given numbers are 618, 864, 25, 605

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

Apply this formula for all numbers.

Step1:

LCM(618, 864) = 88992

GCD(618, 864) = ( 618 x 864 ) / 88992

= 618 / 864

= 618

Step2:

LCM(6, 25) = 150

GCD(6, 25) = ( 6 x 25 ) / 150

= 6 / 25

= 6

Step3:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

So, Greatest Common Divisor of 618, 864, 25, 605 is 1
