Your estimate will be greater than the exact number.
When you round both factors in a multiplication problem up, your estimate will be greater than the actual product.
You cannot have a common factor with only one number. You must have at least 2 to compare the factors.
You cannot have a common factor with only one number. You must have at least 2 numbers to compare factors with.
For a number to have common factors, there needs to be another number to compare its factors with.
The product will be greater than either of the factors.
the lower number for the denominator greater the number is.

A factor means a number that can be multiplied by another number to equal a greater number. (Ex. 3x4=12... in this example 3 and 4 are factors of 12). A common factor is when you compare two numbers factors. (Ex. take all the factors of 12-1,2,3,4,6,12 and compare these with all the factors of 24-1,2,3,4,6,8,12,24). Now look at the factors of 12 and 24 carefully and look at all ofthe common factors. All of the common factors are 1,2,3,4,6 and 12. The greatest common factor is just the one number... 12
Every number greater than 1 has 1 and the number itself as factors. If it has no other factors besides these two factors, it is a prime number. If it has more factors than 1 and itself, it is a composite number.
Every number greater than 1 has the two factors 1 and the number itself.
The number in brackets: 2(2)17 was the only number needed to compare whether 2217 is greater than 2167.
When you wish to compare is to another number.
