If you mean the common factors of 14 and 16, they are 1 and 2. The common multiples of 14 and 16 are 112, 224, 336 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.
The factors of 14 are:1, 2, 7, 14The factors of 63 are:1, 3, 7, 9, 21, 63The common factors are:1, 7
28 is a multiple of 14, so it can be proven that any factor of 14 must be a factor of 28.
Factors of the number will also be factors of the number's multiples. Multiples of the number will also be multiples of the number's factors.
2 and 14
7,147, 14 and 28
1 and 2 are common factors. 84 and 168 are common multiples.
If you mean the common factors of 14 and 16, they are 1 and 2. The common multiples of 14 and 16 are 112, 224, 336 and so on.
Factors: 1, 2, 3, 6, 7, 14, 21, 42 Multiples: 42, 84, 126 and so on.
As 84 = 14 x 6: All the factors of 14 are common to both, ie the common factors of 14 and 84 are: 1, 2, 7, 14; All the multiples of 84 are common to both 14 and 84, ie the common multiples of 14 and 84 are: 84, 168, 252, 336, 420, 504, 588, 672, 756, 840, ...
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 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 create multiples, multiples break down into factors.
Only 2. (or possibly -2 as well).
The factors of 14 are:1, 2, 7, 14The factors of 63 are:1, 3, 7, 9, 21, 63The common factors are:1, 7
28 is a multiple of 14, so it can be proven that any factor of 14 must be a factor of 28.
