Given numbers are 285, 640, 724, 864

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 724 are 2 x 2 x 181

Prime factors of 864 are 2 x 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 285, 640, 724, 864

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

Apply this formula for all numbers.

Step1:

LCM(285, 640) = 36480

GCD(285, 640) = ( 285 x 640 ) / 36480

= 285 / 640

= 285

Step2:

LCM(5, 724) = 3620

GCD(5, 724) = ( 5 x 724 ) / 3620

= 5 / 724

= 5

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 285, 640, 724, 864 is 1
