False. Just because a number has 2 and 4 as factors does not necessarily mean it has 8 as a factor. For a number to have 8 as a factor, it must have both 2 and 4 as factors, but it could also have additional factors that are not necessarily present in numbers with only 2 and 4 as factors. In other words, having 2 and 4 as factors is a necessary but not sufficient condition for a number to have 8 as a factor.

If a number has 2 and 4 as factors then it has 8 as a factor true or false?

false


If a number has 2 and 6 as factors then it has twelve as factors True or false and why?

False. Just because a number has 2 and 6 as factors does not necessarily mean it has 12 as a factor. For example, the number 6 has 2 and 6 as factors, but it does not have 12 as a factor. A number must be divisible by all factors to include a larger factor like 12, which requires it to be divisible by both 3 and 4.


Is it true or false that any number that divides another number with a remainder of 2 is called a factor?

False. Factors divide evenly with no remainder.

Is it true or false that two composite numbers are relatively prime and explain?

Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.

True or false 4 is a factor of 9?

4 is not a factor of 9. The factors of 9 are 1, 3, and 9. The closest factor of 4 is 8.


If s is a factor of 16 then the GCF of s and 16 is 16 True or False?

False. If s is a factor of 16, then the greatest common factor (GCF) of s and 16 would be s, not 16. The GCF is the largest number that divides both numbers evenly, and in this case, that number would be s, the smaller of the two factors.
