What can be divided by 3 and 7?
Numbers that can be divided evenly by both 3 and 7 must be multiples of the least common multiple of 3 and 7, which is 21. Therefore, any number that is a multiple of 21 can be divided by both 3 and 7. Examples of such numbers include 21, 42, 63, 84, and so on.
What number is both a factor and multiple of 7?
The only number that could be both a factor and a multiple is 7 itself.
What is the largest multiple of 3 and 7?
There is no such number. Since if x were the largest multiple of 3 and 7 then what about 2x? 2x would be a multiple of 3 since x is a multiple of 3; 2x would be a multiple of 7 since x is a multiple of 7; and 2x is bigger than x. So x cannot be the largest.
