Given numbers are 280, 845, 612, 905

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 845 are 5 x 13 x 13

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 905 are 5 x 181

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

Given numbers are 280, 845, 612, 905

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

Apply this formula for all numbers.

Step1:

LCM(280, 845) = 47320

GCD(280, 845) = ( 280 x 845 ) / 47320

= 280 / 845

= 280

Step2:

LCM(5, 612) = 3060

GCD(5, 612) = ( 5 x 612 ) / 3060

= 5 / 612

= 5

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 280, 845, 612, 905 is 1
