For 2 to be a factor, the number has to be even. If you multiply two odd numbers together, you get an odd number. 7 is odd, so if I multiply it by any odd number, I will get a number that doesn't have 2 as a factor (e.g. 7x5=35 which doesn't have 2 as a factor). Thus, the answer to the question is "no," not all multiples of 7 have 2 as a factor.

Do all numbers that have 13 as a factor also have 5 as a factor?
Not AllTo find out if all numbers that have 5 as a factor have 2 as a factor, you can list the multiples of each. 5's multiples are 5, 10, 15, 20...2's multiples are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20...5 and 15 are multiples of 5, but not 2, so all numbers that have 5 as a factor DO NOT have 2 as a factor.It is not really necessary to write that all out because the fact that 5 is an odd number and 2 is only a factor of even numbers indicates that all numbers that have 5 as a factor would not have 2 as a factor. Only the multiples of 5 that are even have 2 as a factor also.
What numbers have 4 as a factor?

Why is a multiple of 2 a multiple of 4?
It's not. 4 is a multiple of 2. 2 is a factor of 4 because it can divide into 4 evenly with no remainder.
What multiples of 2 is a factor of 3?
No multiples of 2 are factors of 3.
Are all multiples of 2 greater then 2 are composite numbers explain?
Yes, all multiples of 2 that are greater than 2 are composite numbers. In addition to 1 and the number itself, 2 is a factor of all even numbers.
What numbers have 2 and 3 as their factor?

Why are 8 multiples are fewer than multiples of 2?

Is 2 a factor of 423?
24 can be written as 24 = 4 × 6 = 2 × 2 × 2 × 3
What are the multiples of 16 and 2?
All multiples of 16 are also multiples of 2.
Why are multiples of six even?
Because they contain 2 as a factor.
