Least Common Denominator of 33, 39 and 72 (LCD of 33, 39 and 72)

Least Common Denominator (LCD) of 33, 39, and 72

The Least Common Denominator of 33, 39 and 72, also known as the Lowest Common Denominator of 33, 39 and 72, is useful if you need to add, subtract, or compare three fractions with the denominators of 33, 39 and 72.

The fractions with 33, 39 and 72 denominators will look like this:

		X
		33

		Y
		39

		Z
		72

The Least Common Denominator of 33, 39 and 72 is 10296.

You need to multiply 33 by 312, 39 by 264, and 72 by 143 to make them all 10296. 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 312
		33 x 312

		Y x 264
		39 x 264

		Z x 143
		72 x 143

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

		312X
		10296

		264Y
		10296

		143Z
		10296

You can substitute X, Y and Z with the numerators of your fractions with 33, 39 and 72 denominators. This way you can add, subtract and compare your fractions correctly.
