Least Common Denominator of 2 and 16 (LCD of 2 and 16)

Least Common Denominator (LCD) of 2 and 16

The Least Common Denominator of 2 and 16, also known as the Lowest Common Denominator of 2 and 16, is useful if you need to add, subtract, or compare two fractions with the denominators of 2 and 16.

The fractions with 2 and 16 denominators will look like this:

		X
		2

		Y
		16

The Least Common Denominator of 2 and 16 is 16.

You need to multiply 2 by 8 and 16 by 1 to make them both 16. Furthermore, you need to multiply the numerators by the same amounts to keep the fraction values the same.

Therefore, you have to make the following calculations so the fractions keep the same values and get the same denominator:

		X x 8
		2 x 8

		Y x 1
		16 x 1

Which gives you the following two new fractions that you can add, subtract and compare:

		8X
		16

		1Y
		16

You can substitute X and Y with the numerators of your fractions with 2 and 16 denominators. This way you can add, subtract and compare your fractions correctly.
