Prime numbers are only divisible by 1 and themselves. So, a prime number cannot be divisible by 10. The only prime number that is divisible by 2 is 2 itself; all other numbers divisible by 2 are not prime numbers.

No - but all the numbers divisible by 10 are divisible by 5 !

All numbers divisible by 10 end in zero and all numbers that end in 0 are divisible by 10. ( I am assuming base 10 notation, of course)

All numbers divisible by 90 are also divisible by 9 and 10

Yes, since 10 is divisible by 5, ALL numbers that are divisble by 10 are also divisble by 5.

no because 5,15,25,35,45,55,65,75,85,95,105...are not divisible by 10.10,20,30,40,50,60,70,80,90,100 are divisible by 10 and 5

No. Both are divisible by 5.

143 is not a prime number; it is divisible by 11 and 13.Incidentally, it is divisible by 1; all numbers are.

5,19, 29, 61, 41, 127 10 is divisible by 2 so not prime 49 is divisible by 7 57 is divisible by 3

No all numbers ending in 0 (zero) are divisible by 10 and therfore divisible by at least 5 and 2. 1180 has the prime factors:2 * 2 * 5 * 59

No. 15 is divisible by 5.

Not all of them, if you flipped the question around to ask area numbers divisible by 10 also divisible by 5? then the answer would be yes. The answer is no.

Yes. 10 divided by 1 is 10. All numbers are divisible by 1.

Neither 4 nor 10 is prime. A prime number is a number that is evenly divisibly only by 1 and itself, not any other numbers. 4 is also divisible by 2. 10 is also divisible by 2 and 5. Therefore, both 4 and 10 are composite numbers.

All numbers are divisible by ten but if you are referring to numbers that are divisible by ten and produce a whole number, you are referring to multiples of 10 or any number ending in 0.

No because as for example 25 is evenly divisible by 5 but not by 10

All even numbers are divisible by 2, but all even numbers are not divisible by 4. Some that aren't are 6, 10, 14, 18, 22...

No, but the reverse is true.

Any number that is divisible by 10 is an even number and hence divisible by 2 also. It can also be stated that because 10 is divisible by 2, all numbers divisble by 10 are also divisible by 2.

No. Even numbers are never prime numbers. A prime number is a number that is only divisible by 1 and itself. Even numbers are always divisible by 2, so they are never prime.And 20 is also divisible by 4 and 5. Its factors are 1, 2, 4, 5, 10, and 20.

Well, not technically. You cannot divide 5 by 10 (if you want a positive number that isn't a decimal.) But, ALL NUMBERS THAT ARE DIVISIBLE BY 10 ARE DIVISIBLE BY 5! You just have to turn that question around.

-- All of the numbers that end with a zero are divisible by 10.-- All of those, and all of the numbers that end with a 5, are also divisible by 5.

Yes, since 10 is divisible by 5. Likewise, every number which is divisible by 9 is also divisible by 3.

3, 7 and 47 are prime numbers. 30 is not a prime since it is divisible by 2, 3, 5, 6, 10 and 15.
