Let's deny the premise. I don't think they are opposites. The opposite of a factor is a non-factor or a number that is not a factor and in special cases factors and multiples are the same. 10 is both a factor and a multiple of 10.
5, 10, and 20 are all multiples of 5 and factors of 20.
No.
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.
No. Factor pairs can be combined to create multiples.
Because 10 is a factor of 100.
Any number is a factor and a multiple of itself. Other factors are less than the number, other multiples are more. 5 is a factor of 10. 10 is a multiple of 5.
Yes.

like the multiples of 10 is 1,2,5,10.
If a multiple of 10 were a factor of 45, then both '10' and the multiple would be factors of 45. Since 10 is not a factor of 45, there is no such number.There are no multiples of 10 that are factors of 45.
No, 5 is a factor of 10 and 20. 10 and 20 are multiples of 5.
Any number that has another number for a factor has that number's factors as factors as well. Since 5 is a factor of 10, all multiples of 10 have 5 as a factor.
5, 10, and 20 are all multiples of 5 and factors of 20.
No.

Since 10 is a factor of 20, all multiples of 20 are multiples of 10. This is also true of 1, 2, 4 and 5.
