Best Answer

a number is 6.

All numbers divisible by both 4 and 15 are the multiples of 4 and 15. Since 4 and 15 have no prime factor in common (4 = 22, 15 = 3 · 5), then the least common multiple of 4 and 15 is equal to their product, namely 4 · 15 = 60. Every other multiple of 4 and 15 is divisible by 60. Thus, if 60 is divisible by a number then all the multiples of 4 and 15 are divisible by that number. Therefore, it is enough to check by which number in the given options is 60 divisible. Only 6 divides 60 and none of the other do. The answer must be (A).

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

All numbers that are divisible by 8 and 12 would also be divisible by 4.

Two. All numbers are also divisible by 1.

All numbers divisible by 3 are NOT divisible by 9. As an example, 6, which is divisible by 3, is not divisible by 9. However, all numbers divisible by 9 are also divisible by 3 because 9 is divisible by 3.

no

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

No, because 1 is not evenly divisible by 5. However, all numbers divisible by 5 are divisible by 1.

Yes.

Yes.

Yes. Test a couple numbers divisible by 9--27, 81--and they are all divisible by 3.

No. 15 is divisible by 5.

Yes, if you are referring to whole numbers.

All multiples of 6 are evenly divisible by 6, such as: 6, -6, 12, -12, 18, -18, and so on. Numbers divisible by six must also be divisible by both 2 and 3.

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.

no, 18 is divisible by 9 but not by 4.

No, but the reverse is true.

-- 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.

-- 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.

No, they are both even and odd. The numbers 18 and 36 are examples of even numbers divisible by nine.

Not all even numbers are divisible by 6. These numbers are not evenly divisible by 6: Any number smaller than 6. Any number not divisible by 3. If a number is divisible by both 2 and 3, it is divisible by 6.

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

All numbers are divisible by 1.

All numbers divisible by 9 are divisible by 3; since 9 = 3 x 3 all multiples of 9 are also multiples of 3. However, all numbers divisible by 3 are not divisible by 9, eg 6 = 2 x 3 but 6 is not divisible by 9 (since 6 is not a multiple of 9) - it only takes one counter example to disprove a theory.
