GCD of numbers is the greatest common divisor

So, the GCD (80, 82, 18, 13) = 1.

Given numbers are 80, 82, 18, 13

The list of prime factors of all numbers are

Prime factors of 80 are 2 x 2 x 2 x 2 x 5

Prime factors of 82 are 2 x 41

Prime factors of 18 are 2 x 3 x 3

Prime factors of 13 are 13

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

Given numbers are 80, 82, 18, 13

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

Apply this formula for all numbers.

Step1:

LCM(80, 82) = 3280

GCD(80, 82) = ( 80 x 82 ) / 3280

= 80 / 82

= 80

Step2:

LCM(2, 18) = 18

GCD(2, 18) = ( 2 x 18 ) / 18

= 2 / 18

= 2

Step3:

LCM(2, 13) = 26

GCD(2, 13) = ( 2 x 13 ) / 26

= 2 / 13

= 2

So, Greatest Common Divisor of 80, 82, 18, 13 is 1
