Factors: 1, 3, 7, 21 Multiples: 21, 42, 63, 84 and so on.
the answer i know is 42 and 56 wrong! the multiples of 42 is 42,84,126,168 and etc.
The lowest common multiple of the two numbers is 42. All multiples of 42 are common multiples of 6 and 7. So the common multiples of 6 and 7 are 42, 84, 126, 168, 210, 252, 294, 336, and so on.
It is always useful to know about factors and multiples.
Factors go into numbers, numbers go into multiples.
Factors go into numbers, numbers go into multiples. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42 Multiples of 42: 42, 84, 126 and so on.
Factors: 1, 2, 3, 6, 7, 14, 21, 42 Multiples: 42, 84, 126 and so on.
The factors of 7 are 1 and 7. Neither of them are multiples of 42. Put the other way, 7, 14, 21 and 42 are multiples of 7 that are factors of 42.
Factors: 1, 3, 7, 21 Multiples: 21, 42, 63, 84 and so on.
Multiples don't add. Addends add, like 13 + 14 + 15 = 42 but I suspect you want factors, specifically prime factors. 2 x 3 x 7 = 42
1344 is a multiple of 42. 42 is a factor of 1344. Factors go into numbers, numbers go into multiples.
