Every number with a factor of 10 must have factors of 2 and 5. This is because 10 can be expressed as 2 x 5. Any number that is a multiple of 10 will have both 2 and 5 as factors, along with any other factors it may have. These two prime factors are essential for a number to have a factor of 10.

What is the relation of the factors of a number to its multiples?
Not sure what the question means so two possible answers: A1: Every factor of a number must be a factor of all its multiples (though the converse does not apply). A2: Some numbers (eg primes) have no proper factors, others have many. But all numbers can be multiplied by any other number.
