Given numbers are 74, 57, 81

The list of prime factors of all numbers are

Prime factors of 74 are 2 x 37

Prime factors of 57 are 3 x 19

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

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

Given numbers are 74, 57, 81

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

Apply this formula for all numbers.

Step1:

LCM(74, 57) = 4218

GCD(74, 57) = ( 74 x 57 ) / 4218

= 74 / 57

= 74

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

So, Greatest Common Divisor of 74, 57, 81 is 1
