Given numbers are 864, 646, 714, 905

The list of prime factors of all numbers are

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

Prime factors of 646 are 2 x 17 x 19

Prime factors of 714 are 2 x 3 x 7 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 864, 646, 714, 905

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

Apply this formula for all numbers.

Step1:

LCM(864, 646) = 279072

GCD(864, 646) = ( 864 x 646 ) / 279072

= 864 / 646

= 864

Step2:

LCM(2, 714) = 714

GCD(2, 714) = ( 2 x 714 ) / 714

= 2 / 714

= 2

Step3:

LCM(2, 905) = 1810

GCD(2, 905) = ( 2 x 905 ) / 1810

= 2 / 905

= 2

So, Greatest Common Divisor of 864, 646, 714, 905 is 1
