Therefore, highest odd number that is a factor of 60 and a factor of 90 is 15.

Answer 2

The highest odd number is 15.

Here for determining the highest odd number we first need to determine:

• The factor of 60.
• The factor of 90.

So,

The factor of 60 be $2\times 2 \times 3 \times 5$

And, the factor of 90 be $2 \times 3 \times 3 \times 5$
