Given numbers are 816, 705, 859, 715

The list of prime factors of all numbers are

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 705 are 3 x 5 x 47

Prime factors of 859 are 859

Prime factors of 715 are 5 x 11 x 13

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

Given numbers are 816, 705, 859, 715

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

Apply this formula for all numbers.

Step1:

LCM(816, 705) = 191760

GCD(816, 705) = ( 816 x 705 ) / 191760

= 816 / 705

= 816

Step2:

LCM(3, 859) = 2577

GCD(3, 859) = ( 3 x 859 ) / 2577

= 3 / 859

= 3

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 816, 705, 859, 715 is 1
