GCD of numbers is the greatest common divisor

So, the GCD (16, 81, 14, 25) = 1.

Given numbers are 16, 81, 14, 25

The list of prime factors of all numbers are

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

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

Prime factors of 14 are 2 x 7

Prime factors of 25 are 5 x 5

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

Given numbers are 16, 81, 14, 25

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

Apply this formula for all numbers.

Step1:

LCM(16, 81) = 1296

GCD(16, 81) = ( 16 x 81 ) / 1296

= 16 / 81

= 16

Step2:

LCM(1, 14) = 14

GCD(1, 14) = ( 1 x 14 ) / 14

= 1 / 14

= 1

Step3:

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

= 1 / 25

= 1

So, Greatest Common Divisor of 16, 81, 14, 25 is 1
