Least Common Denominator of 2, 4 and 13 (LCD of 2, 4 and 13)

Least Common Denominator (LCD) of 2, 4, and 13

The Least Common Denominator of 2, 4 and 13, also known as the Lowest Common Denominator of 2, 4 and 13, is useful if you need to add, subtract, or compare three fractions with the denominators of 2, 4 and 13.

The fractions with 2, 4 and 13 denominators will look like this:

		X
		2

		Y
		4

		Z
		13

The Least Common Denominator of 2, 4 and 13 is 52.

You need to multiply 2 by 26, 4 by 13, and 13 by 4 to make them all 52. 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 value and get the same denominator:

		X x 26
		2 x 26

		Y x 13
		4 x 13

		Z x 4
		13 x 4

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

		26X
		52

		13Y
		52

		4Z
		52

You can substitute X, Y and Z with the numerators of your fractions with 2, 4 and 13 denominators. This way you can add, subtract and compare your fractions correctly.
