The factor tree finds the prime factorization of a given number. Combining the prime factorizations of two denominators correctly will give you their least common denominator.
find the lowest factor that equals the numerator and denominator.
The least common factor is 1, I think you mean the greatest common factor which is 3.
If you're wanting to find a common denominator between fractions with denominators of 3 and 2, then 3 & 2 have only a common factor of 1, so the least common denominator = 2*3 = 6
You need at least two numbers to find a common denominator.
When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .
The least common denominator is 144.
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
least common denominator is nothing but least common multiple of denominators.
You write 8 over 100: 8/100. To simplify, look for a common factor between the numerator and the denominator. If you find any, divide numerator and denominator by the common factor. Repeat, until you find no more common factors.You write 8 over 100: 8/100. To simplify, look for a common factor between the numerator and the denominator.

That's one fraction. You need at least two to find something in common between them.
The way that you can find the least common denominator is by first multiplying the 2 bottom numbers and whatever the product is that is your common denominator. to find the smallest one, you have to keep dividing it till it is in counting order or there is an odd number.
Least common multiple is needed to find the least common denominator when adding or subtracting fractions with different denominators Greatest common factor is needed when reducing fractions to their lowest terms
