multiply the denominators
You use them when there are 2 fractions with different denominators.
Every set of denominators has a common denominator, even if it's only their product.
When you're adding or subtracting fractions with different denominators, if you multiply the denominators that's your Quick Common Denominator. I'ts useful for denominators that don't have a low Least Common Factor.
By finding the lowest common multiple of the different denominators then rearranging the numerators and denominators accordingly.
The LCM is: 55,125
Common multiples and common denominators can be found using the same process. They differ in their function. Common denominators are common multiples that are functioning as denominators.
735 over 1
Common denominators are common multiples of two or more denominators.
Denominators which have no common factors
The least common denominator is the least common multiple of the denominators.
Greatest common factor of 350 and 735 is 35.
The Highest Common Factor of 735 and 1050 is 105.
HCF(735, 2625) = 105
multiply the denominators
The least common multiple of the denominators is knows as the LCD or least common denominator.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
