GCD of numbers is the greatest common divisor

So, the GCD (81, 13, 82, 58) = 1.

Given numbers are 81, 13, 82, 58

The list of prime factors of all numbers are

Prime factors of 81 are 3 x 3 x 3 x 3

Prime factors of 13 are 13

Prime factors of 82 are 2 x 41

Prime factors of 58 are 2 x 29

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

Given numbers are 81, 13, 82, 58

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

Apply this formula for all numbers.

Step1:

LCM(81, 13) = 1053

GCD(81, 13) = ( 81 x 13 ) / 1053

= 81 / 13

= 81

Step2:

LCM(1, 82) = 82

GCD(1, 82) = ( 1 x 82 ) / 82

= 1 / 82

= 1

Step3:

LCM(1, 58) = 58

GCD(1, 58) = ( 1 x 58 ) / 58

= 1 / 58

= 1

So, Greatest Common Divisor of 81, 13, 82, 58 is 1
