Least Common Denominator of 2, 4 and 89 (LCD of 2, 4 and 89)

Least Common Denominator (LCD) of 2, 4, and 89

The Least Common Denominator of 2, 4 and 89, also known as the Lowest Common Denominator of 2, 4 and 89, is useful if you need to add, subtract, or compare three fractions with the denominators of 2, 4 and 89.

The fractions with 2, 4 and 89 denominators will look like this:

		X
		2

		Y
		4

		Z
		89

The Least Common Denominator of 2, 4 and 89 is 356.

You need to multiply 2 by 178, 4 by 89, and 89 by 4 to make them all 356. 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 178
		2 x 178

		Y x 89
		4 x 89

		Z x 4
		89 x 4

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

		178X
		356

		89Y
		356

		4Z
		356

You can substitute X, Y and Z with the numerators of your fractions with 2, 4 and 89 denominators. This way you can add, subtract and compare your fractions correctly.
