We need to colour the prime number row in orange.

Prime number is a number that is divisible only by itself and $1$ .

We should not colour the odd numbers row.

Odd numbers are numbers that ends with $1, 3, 5, 7, 9$ .

So, $1, 3, 5, 7, 9, 11, 13, 15, 17$ are odd numbers.

We need to colour the multiples of $6$ row in blue.

Multiples, are numbers that we get when we multiply one whole number by another whole number.

Square is the product of some integer with itself.

So, $36$ are square numbers.

We should not colour the even numbers.

Even numbers always end up with the last digit as $0, 2, 4, 6 or 8$ .

So, $2, 4, 6, 8, 10, 12, 14, 16, 18$ are even numbers.

We should colour multiple of $8$ row by blue.

Multiples, are numbers that we get when we multiply one whole number by another whole number.

By using the table of $8$ we can obtain the multiple of $8$ .

So, $8, 16, 24, 32, 40, 48, 56, 64, 72$ are multiples of $8$ .

Hence, the completed table is shown above.
