Given numbers are 81, 29, 19, 16

The list of prime factors of all numbers are

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

Prime factors of 29 are 29

Prime factors of 19 are 19

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 81, 29, 19, 16

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

Apply this formula for all numbers.

Step1:

LCM(81, 29) = 2349

GCD(81, 29) = ( 81 x 29 ) / 2349

= 81 / 29

= 81

Step2:

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

= 1 / 19

= 1

Step3:

LCM(1, 16) = 16

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

= 1 / 16

= 1

So, Greatest Common Divisor of 81, 29, 19, 16 is 1
