GCD of numbers is the greatest common divisor

So, the GCD (81, 38, 46, 74) = 1.

Given numbers are 81, 38, 46, 74

The list of prime factors of all numbers are

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

Prime factors of 38 are 2 x 19

Prime factors of 46 are 2 x 23

Prime factors of 74 are 2 x 37

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

Given numbers are 81, 38, 46, 74

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

Apply this formula for all numbers.

Step1:

LCM(81, 38) = 3078

GCD(81, 38) = ( 81 x 38 ) / 3078

= 81 / 38

= 81

Step2:

LCM(1, 46) = 46

GCD(1, 46) = ( 1 x 46 ) / 46

= 1 / 46

= 1

Step3:

LCM(1, 74) = 74

GCD(1, 74) = ( 1 x 74 ) / 74

= 1 / 74

= 1

So, Greatest Common Divisor of 81, 38, 46, 74 is 1
