## How do you find the greatest divisor?

How to Find the Greatest Common Divisor Using LCM Method?

- Step 1: Determine the product of a and b.
- Step 2: Now, find the least common multiple (LCM) of a and b.
- Step 3: Divide the values obtained in Step 1 and Step 2.
- Step 4: The obtained value after division is the greatest common divisor of (a, b).
