So the Greatest Common Divisior 45, 85, 60, 65 is 5.

Therefore, GCD of numbers 45, 85, 60, 65 is 5

Given Input Data is 45, 85, 60, 65

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 85 is 5 x 17

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 65 is 5 x 13

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

Step1:

Let's calculate the GCD of first two numbers

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

LCM(45, 85) = 765

GCD(45, 85) = ( 45 x 85 ) / 765

GCD(45, 85) = 3825 / 765

GCD(45, 85) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 60

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

LCM(5, 60) = 60

GCD(5, 60) = ( 5 x 60 ) / 60

GCD(5, 60) = 300 / 60

GCD(5, 60) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 65

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

LCM(5, 65) = 65

GCD(5, 65) = ( 5 x 65 ) / 65

GCD(5, 65) = 325 / 65

GCD(5, 65) = 5

GCD of 45, 85, 60, 65 is 5
