Given numbers are 816, 956, 169, 646

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 956 are 2 x 2 x 239

Prime factors of 169 are 13 x 13

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 816, 956, 169, 646

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

Apply this formula for all numbers.

Step1:

LCM(816, 956) = 195024

GCD(816, 956) = ( 816 x 956 ) / 195024

= 816 / 956

= 816

Step2:

LCM(4, 169) = 676

GCD(4, 169) = ( 4 x 169 ) / 676

= 4 / 169

= 4

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 816, 956, 169, 646 is 1
