Least Common Denominator of 61, 72 and 82 (LCD of 61, 72 and 82)

Least Common Denominator (LCD) of 61, 72, and 82

The Least Common Denominator of 61, 72 and 82, also known as the Lowest Common Denominator of 61, 72 and 82, is useful if you need to add, subtract, or compare three fractions with the denominators of 61, 72 and 82.

The fractions with 61, 72 and 82 denominators will look like this:

		X
		61

		Y
		72

		Z
		82

The Least Common Denominator of 61, 72 and 82 is 180072.

You need to multiply 61 by 2952, 72 by 2501, and 82 by 2196 to make them all 180072. 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 2952
		61 x 2952

		Y x 2501
		72 x 2501

		Z x 2196
		82 x 2196

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

		2952X
		180072

		2501Y
		180072

		2196Z
		180072

You can substitute X, Y and Z with the numerators of your fractions with 61, 72 and 82 denominators. This way you can add, subtract and compare your fractions correctly.
