Denominators are just numbers. Factoring them into primes meanss finding their prime factorizations. A factor tree can help you visualize this.

What does it mean when you multiply the numerator and the denominator of a ratio by the same factor?
You will get an equivalent fraction.
What does it mean to divide the numerator and the denominator of a ratio by the same factor?
It means that the previous fraction was not in its lowest terms.
Why do the fours in the numerator and denominator cancel out?
They are a common factor and any common factor in the numerator and denominator of a ratio can be cancelled out.
Writing a number as the product of primes is called writing its?
Factor tree.
Factor 93 into a productof primes?
93 = 3 x 31
How is four over five is in simplest form?
Great question! :)The numerator and denominator are relatively prime.If you factor the numerator into the product of its primes, and factor the denominator into its product of primes, there are no primes to cancel:4 / 5 = 2 * 2 / 5since the only primes in the numerator are 2, and the only ones in the denominator are 5, they cannot divide into each other for further simplication.For a contrast, consider 4 / 6.Here you can rewrite 4 / 6 as (2 * 2) / (2 * 3).In this case, a 2 in the numerator cancels with a 2 in the denominator, reducing the fraction to 2/3. One way of visualizing the cancellation is below:(2 * 2) / (2 * 3) = 2 / 3.
Is one a greatest common factor?
It can be, if you're comparing primes or relative primes.
What is the common denominator of 4 and 8?
if you mean common factor then it is 4

What does LCD and GCF mean in math?
LCD:Lowest Common Denominator GCF:Greatest Common Factor
What does scaling down mean?
Means to multipily the numerator and the denominator of a ratio by the same factor.
When you divide the numerator and denominator by the same factor?
when you divide the numerator and denominator by the same factor
What is the greatest common factor 56 and 81?
Factor each to primes then, choose the common primes to multiply.56=2x2x2x781=3x3x3x3Greatest common is the multiplication identity 1.
What is a distinct odd prime?
When a factor of a number is composed of distinct primes, all the odd primes are raised to a power of 1, while the only even number which is 2 can be raised to any power. For example, the factor of 2134346 is 2*19*56167 Here all the primes are distinct primes.
When you factor a number into its primes 2 is a factor then you know that the last digit must be what?
Even.
What means to discuss the numerator and the denominator of a ration but the same factor?
The phrase in the question does not mean anything!
