Given numbers are 13, 79, 68, 16

The list of prime factors of all numbers are

Prime factors of 13 are 13

Prime factors of 79 are 79

Prime factors of 68 are 2 x 2 x 17

Prime factors of 16 are 2 x 2 x 2 x 2

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

Given numbers are 13, 79, 68, 16

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

Apply this formula for all numbers.

Step1:

LCM(13, 79) = 1027

GCD(13, 79) = ( 13 x 79 ) / 1027

= 13 / 79

= 13

Step2:

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

= 1 / 68

= 1

Step3:

LCM(1, 16) = 16

GCD(1, 16) = ( 1 x 16 ) / 16

= 1 / 16

= 1

So, Greatest Common Divisor of 13, 79, 68, 16 is 1
