Least common multiple of 3 and 7?
The (LCM) Least Common Multiple of 7 and 3 is 21 because that is the LEAST number that both 3 and 7 go into.
Which number is a common multiple of 7 and 4?
The smallest number which is a common multiple of both 7 and 4 is 28.
What is the smallest number that is a multiple of both 5 and 7?
The lowest common multiple of 5 and 7 is 35.
What number is a factor of 21 but not a multiple of 7?
The factors of 21 are 1, 3, 7, 21. The factors which are not a multiple of 7 are 1 and 3.
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.
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.
