## GCF of 24 and 32 by Long Division Method.

Divide the Larger Number by the Smaller Number:

Divide 32 (larger number) by 24 (smaller number).

32 ÷ 24 = 1 remainder 8

Replace the Larger Number with the Smaller Number:

The divisor (24) becomes the new dividend.

The remainder (8) becomes the new divisor.

Repeat the Division:

Now, divide 24 by 8.

24 ÷ 8 = 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 8.
