Given numbers are 100, 289, 805, 285

The list of prime factors of all numbers are

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 289 are 17 x 17

Prime factors of 805 are 5 x 7 x 23

Prime factors of 285 are 3 x 5 x 19

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

Given numbers are 100, 289, 805, 285

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

Apply this formula for all numbers.

Step1:

LCM(100, 289) = 28900

GCD(100, 289) = ( 100 x 289 ) / 28900

= 100 / 289

= 100

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 100, 289, 805, 285 is 1
