Given numbers are 27, 67, 71, 15

The list of prime factors of all numbers are

Prime factors of 27 are 3 x 3 x 3

Prime factors of 67 are 67

Prime factors of 71 are 71

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 27, 67, 71, 15

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

Apply this formula for all numbers.

Step1:

LCM(27, 67) = 1809

GCD(27, 67) = ( 27 x 67 ) / 1809

= 27 / 67

= 27

Step2:

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

= 1 / 71

= 1

Step3:

LCM(1, 15) = 15

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

= 1 / 15

= 1

So, Greatest Common Divisor of 27, 67, 71, 15 is 1
