## GCF of 24 and 28 by Long Division Method.

To find the Greatest Common Factor (GCF) of 24 and 28 using the Long Division Method, follow these simple steps:

### Step-by-Step Process:

**Divide the Larger Number by the Smaller Number:**

Divide 28 (larger number) by 24 (smaller number).

28 ÷ 24 = 1 remainder 4

**Replace the Larger Number with the Smaller Number:**

The divisors (24) becomes the new dividend.

The remainder (4) becomes the new divisor.

**Repeat the Division:**

Now, divide 24 by 4.

24 ÷ 4 = 6 remainder 0

**Check the Remainder:**

When the remainder is 0, the current divisor is the GCF.

The remainder is 0, and the current divisor is 4.
