The answer will depend on the problem!
That seems like a fairly easy choice...
Factors,are the number that can be multiply and multiplies are the operation to solve a problem and to factorize numbers...
you list all the multiples of each number until you come to the first number that is in all columns
This cannot be answered because the common multiples of any two or more numbers are infinite.
The hcf is useful in reducing fractions to their lowest terms and the lcm is useful in finding the lowest common denominator of fractions that have different denominators that need to be added or subtracted.
Example: 30 and 42Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Select the common factors.2 x 3 = 6, the GCForList the factors.1, 2, 3, 5, 6, 10, 15, 301, 2, 3, 6, 7, 14, 21, 42
There are many problems involving factors and the question needs to be more specific.
21 and 84
You make make a factor tree to solve this:24 = 6 * 4 = 3 * 2 * 2 * 2Therefore, the factors of 24 which are multiples of 3 are 3, and 3*2 = 6, and 3*2*2 = 12
the cast of finding nemo is going to have a party there will be 80 cookies and 20 juice boxes. how many of each will each cast member get?
The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.
