No. Only 14 and multiples of 14 have both 7 and 2 as factors.
Because 3 is a factor of 9. Any number that has a composite number as a factor will also have that number's factors as factors.
is because....
All factors of 18 are factors of 36, because 18 itself is a factor of 36.
No. 6 has 3 as a factor. 12 has 3 as a factor.
5 is a factor of any whole number ending in 5; it is also a factor of any whole number of 2 or more digits ending in zero.
Listen up, honey. If a number has 10 as a factor, that means it can be divided evenly by 10. And guess what? Any number that can be divided by 10 can also be divided by 5 because 10 is just 5 times 2. So, yes, any number that has 10 as a factor will also have 5 as a factor. Case closed.
Because 3 is a factor of 9. Any number that has a composite number as a factor will also have that number's factors as factors.
Any number is divisible by its factors.
Correct. 5 and 2 are factors of 10, and will be factors of any number having 10 as a factor.
Every such number has.
not necessarily.
is because....
All factors of 18 are factors of 36, because 18 itself is a factor of 36.
Yes.
No, that's just a factor. A common factor is when that factor is also a factor of another number.
No. 6 has 3 as a factor. 12 has 3 as a factor.
5 is a factor of any whole number ending in 5; it is also a factor of any whole number of 2 or more digits ending in zero.
