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 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 278 are 2 x 139

Prime factors of 659 are 659

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

Given numbers are 816, 945, 278, 659

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

Apply this formula for all numbers.

Step1:

LCM(816, 945) = 257040

GCD(816, 945) = ( 816 x 945 ) / 257040

= 816 / 945

= 816

Step2:

LCM(3, 278) = 834

GCD(3, 278) = ( 3 x 278 ) / 834

= 3 / 278

= 3

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 816, 945, 278, 659 is 1
