Given numbers are 37, 71, 81, 15

The list of prime factors of all numbers are

Prime factors of 37 are 37

Prime factors of 71 are 71

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

Prime factors of 15 are 3 x 5

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

Given numbers are 37, 71, 81, 15

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

Apply this formula for all numbers.

Step1:

LCM(37, 71) = 2627

GCD(37, 71) = ( 37 x 71 ) / 2627

= 37 / 71

= 37

Step2:

LCM(1, 81) = 81

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

= 1 / 81

= 1

Step3:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

So, Greatest Common Divisor of 37, 71, 81, 15 is 1
