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....
Because 3 is a factor of 9.
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.
Any number that has another number for a factor has that number's factors as factors as well. Since 5 is a factor of 10, all multiples of 10 have 5 as a factor.
Any number is divisible by its 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.
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....
Yes.
No, that's just a factor. A common factor is when that factor is also a factor of another number.
Because 3 is a factor of 9.
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.
