Given numbers are 38, 75, 47, 13

The list of prime factors of all numbers are

Prime factors of 38 are 2 x 19

Prime factors of 75 are 3 x 5 x 5

Prime factors of 47 are 47

Prime factors of 13 are 13

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

Given numbers are 38, 75, 47, 13

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

Apply this formula for all numbers.

Step1:

LCM(38, 75) = 2850

GCD(38, 75) = ( 38 x 75 ) / 2850

= 38 / 75

= 38

Step2:

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

= 1 / 47

= 1

Step3:

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

= 1 / 13

= 1

So, Greatest Common Divisor of 38, 75, 47, 13 is 1
