Lowest Common Denominator (LCD) // Julie's super scribe




My super scribe is about lowest common denominator

What is LCD?
**Lowest common denominator is the least common multiple of the denominators of a set of common fractions.

To find the least common denominator, you have to find the least common multiple.



You have to find the lowest common multiple of 4 and six.

To find the lowest common multiple you have to list the factors of 4 and 6

Four: 4 8 12 16 20 24 ... and so on
Six : 6 12 18 24 30 36 ..... an so on

so The lowest common denominator of 3/4 and 5/6 is 12 because thats the least commmon multiple. Its not 24 because 12 comes first.

<--- how to get the numerator.
