Given numbers are 215, 845, 450, 768

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 845 are 5 x 13 x 13

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 215, 845, 450, 768

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

Apply this formula for all numbers.

Step1:

LCM(215, 845) = 36335

GCD(215, 845) = ( 215 x 845 ) / 36335

= 215 / 845

= 215

Step2:

LCM(5, 450) = 450

GCD(5, 450) = ( 5 x 450 ) / 450

= 5 / 450

= 5

Step3:

LCM(5, 768) = 3840

GCD(5, 768) = ( 5 x 768 ) / 3840

= 5 / 768

= 5

So, Greatest Common Divisor of 215, 845, 450, 768 is 1
