Answer:

1. 180

2. 135

3. 900

4. 216

Step-by-step explanation:

1. As both numbers are both divisible by 6, take out 6. Then the equation will be:

$6 \left[\begin{array}{ccc}30&36\end{array}\right]$

5 6

Then below 30, you put 5. Below 36, you put 6. Why? Because 30 ÷ 6 = 5, 36 ÷ 6 = 6

Then you'll multiply 6, 5 and 6. Then you will get 180.

2. Both numbers are divisible by 3. Take out 3. Then below 27, you put 9. Below 45, you put 15. 27 ÷ 3 = 9, 45 ÷ 3 = 15. Then the equation will be:

$> 9 5As long as the quotient is still dividable, you won't stop dividing it. So 9 and 15 is still divisible to 3. Below 9, you put 3. Below 15, you put 5. There the two quotients are not dividable anymore.<img src=$

4 9 15

Bring down any numbers that are not evenly divisible by the current factor. Take out 3. Just bring down 4. Below 9, you put 3. Below 15, you put 5. 9 ÷ 3 = 3, 15 ÷ 3 = 5.

$> 4 3 5Then multiply 5, 4, 3, and 5. You'll get 900. 4. Both numbers are divisible by 2. Take out 2. Then below 54, you put 27. Below 72, you put 36. 54 ÷ 2 = 27, 72 ÷ 2 = 36. Then the equation will be:<img src=$

27 36

Still dividable, but both divisible by 3. Below 27, put 9. Below 36, put 12. 27 ÷ 3 = 9, 36 ÷ 3 = 12. Then the equation will be:

$> 9 12Both divisible by 3. Below 9, put 3. Below 12, put 4. 9 ÷ 3 = 3, 12 ÷ 3 = 4. Then the equation will be:<img src=$
