14 is a MULTIPLE OF 7 and 14.
Multiple is the result of multiplying a number by an integer.
14 is a multiple of 7 because 7 * 2 = 14
14 is a multiple of 14 because 14 * 1 = 14
A multiple is different from a factor.
If a multiple is the result of multiplying a number by an integer, a factor, on the other hand, is either the number or integer being multiplied to get the multiple.
Example of 14 as a factor:
14 * 2 = 28 ; 14 and 2 are factors of 28
