Least Common Denominator of 35, 39 and 45 (LCD of 35, 39 and 45)

Least Common Denominator (LCD) of 35, 39, and 45

The Least Common Denominator of 35, 39 and 45, also known as the Lowest Common Denominator of 35, 39 and 45, is useful if you need to add, subtract, or compare three fractions with the denominators of 35, 39 and 45.

The fractions with 35, 39 and 45 denominators will look like this:

		X
		35

		Y
		39

		Z
		45

The Least Common Denominator of 35, 39 and 45 is 4095.

You need to multiply 35 by 117, 39 by 105, and 45 by 91 to make them all 4095. 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 117
		35 x 117

		Y x 105
		39 x 105

		Z x 91
		45 x 91

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

		117X
		4095

		105Y
		4095

		91Z
		4095

You can substitute X, Y and Z with the numerators of your fractions with 35, 39 and 45 denominators. This way you can add, subtract and compare your fractions correctly.
