Yes.
No, because as for example 30 is a multiple of 5 but not of 25
Nothing everything is composite
Since you didn't specify a single number, and all numbers are multiples of themselves, the five smallest multiples are the counting numbers 1 to 5.
5, 10, and 20 are all multiples of 5 and factors of 20.
All numbers do.
That's an infinite list. All the multiples of 8 are composite.
Yes, all multiples of 3 are composite except for 3 itself which is a prime number.
245 is not prime. Composite: (5 x 49 or 5 x 7 x 7) Also you can automatically determine a number as composite if: it ends with 2, 4, 6, 8, and 0: multiples of 2; or it ends with 5: multiples of 5.
No, multiples of prime numbers are composite.
No 28 is a composite number and not a multiple of 3
Multiples of any number greater than one are composite.
It is prime because its multiples are 1 and itself that is a prime number
Since 10 is a multiple of 5, all multiples of 10 are multiples of 5.
Since 10 is a multiple of 5, all multiples of 10 will also be multiples of 5. Test the theory. 30, 50, 100... All multiples of 10, and also of 5.
All decimals, and all whole numbers that do not end in zero or 5, are not multiples of 5 .
False, all multiples of 10 end in 0. All multiples of 5 end in 5 or 0.
Multiples of 50 are the only numbers that are both. All other multiples of 5 aren't.
