This is the seventh number in… More …
Is there a factor of 3 in 7?
Unlike 6, there is no factor of 3 in 7 and so not every multiple of 7 has a factor of 3: in order to be a multiple of both 3 and 7, a number must be a multiple of 21. One important difference in the multiples of 6 and 7 that appear in the list of multiples of 3 is that every multiple of 6 is also a multiple of 3.
Which is the least common multiple of 3 and 7?
Since 21 is the first number they have in common, 21 is the least common multiple of 3 and 7. Note: Our lists are shortened because they go on forever, but can you see the pattern when you look at the answer in green above?
Which is the only number that is a multiple of 7?
The only number in the list that is a multiple of 7 is 21 which is. If we write the list of multiples of 7: and then extend the list of multiples of 3: we can see that the first four multiples of 7 that appear in the list of multiples of 3 are 21, 42, 63, and 84. 21 is. We got 42 as a multiple of 7 because.
What are the first five multiples of 3?
The first five multiples of 3 are 3, 6, 9, 12, and 15.
Which is a multiple of the number 6?
0 × 6 = 0, so 0 is a multiple of 6. 1 × 6 = 6, so 6 is a multiple of 6. 2 × 6 = 12, so 12 is a multiple of 6. and so on.
What are the multiples of a given number?
Multiply the given number by 1,2,3, etc. The products are multiple of the given number. Multiple of 3 are 3 (=3 * 1), 6 (=3 * 2), 9(=3*3), 12(=3*4), etc Multiples Test © 2010 UncleMath.com
