GCD(4, 5) = 1.
To find the ratio of the numbers 9, 5, 4, and 7, you simply express them as a fraction of their greatest common divisor (GCD). Since the GCD of these numbers is 1, the ratio remains as 9:5:4:7. Thus, the ratio of 9, 5, 4, and 7 is 9:5:4:7.
To simplify the numbers 4 and 8, you can find their greatest common divisor (GCD), which is 4. Dividing both numbers by their GCD, you get 4 ÷ 4 = 1 and 8 ÷ 4 = 2. Therefore, the simplified form of 4 and 8 is 1 and 2, respectively.
Greatest Common Divisor (GCD) for 12 8 is 4.
The largest number that can divide both 21 and 14 is their greatest common divisor (GCD). To find the GCD, we can list the factors of each number: the factors of 21 are 1, 3, 7, and 21, while the factors of 14 are 1, 2, 7, and 14. The largest common factor is 7, so the GCD of 21 and 14 is 7.
