## GCF of 36 and 48 by Long Division Method.

To find the Greatest Common Factor (GCF) of 36 and 48 using the Long Division Method, follow these steps:

### Step-by-Step Process:

Divide the Larger Number by the Smaller Number:

Divide 48 (larger number) by 36 (smaller number).

48 ÷ 36 = 1 remainder 12

Replace the Larger Number with the Smaller Number:

The divisor (36) becomes the new dividend.

The remainder (12) becomes the new divisor.

Repeat the Division:

Now, divide 36 by 12.

36 ÷ 12 = 3 remainder 0

Check the Remainder:

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

The remainder is 0, and the current divisor is 12.
