Given numbers are 75, 47, 65, 85

The list of prime factors of all numbers are

Prime factors of 75 are 3 x 5 x 5

Prime factors of 47 are 47

Prime factors of 65 are 5 x 13

Prime factors of 85 are 5 x 17

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

Given numbers are 75, 47, 65, 85

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

Apply this formula for all numbers.

Step1:

LCM(75, 47) = 3525

GCD(75, 47) = ( 75 x 47 ) / 3525

= 75 / 47

= 75

Step2:

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

= 1 / 65

= 1

Step3:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

So, Greatest Common Divisor of 75, 47, 65, 85 is 1
