Least Common Denominator of 2, 4 and 22 (LCD of 2, 4 and 22)

Least Common Denominator (LCD) of 2, 4, and 22

The Least Common Denominator of 2, 4 and 22, also known as the Lowest Common Denominator of 2, 4 and 22, is useful if you need to add, subtract, or compare three fractions with the denominators of 2, 4 and 22.

The fractions with 2, 4 and 22 denominators will look like this:

		X
		2

		Y
		4

		Z
		22

The Least Common Denominator of 2, 4 and 22 is 44.

You need to multiply 2 by 22, 4 by 11, and 22 by 2 to make them all 44. 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 22
		2 x 22

		Y x 11
		4 x 11

		Z x 2
		22 x 2

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

		22X
		44

		11Y
		44

		2Z
		44

You can substitute X, Y and Z with the numerators of your fractions with 2, 4 and 22 denominators. This way you can add, subtract and compare your fractions correctly.
