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).

Are all even numbers divisible by 6?
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.
Are all numbers that are divisible by 5 also divisible by 10?
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.
What is the number that is divisible by 1-15?
16
What numbers are divisible by 6?
All multiples of 6 Numbers are evenly divisible by 6 if they are evenly divisible by both 2 AND 3. Even numbers are always evenly divisible by 2. Numbers are evenly divisible by 3 if the sum of all the individual digits is evenly divisible by 3. For example, the sum of the digits for the number 3627 is 18, which is evenly divisible by 3 but 3627 is an odd number so the number 3627 is not evenly divisible by 6
Why are all prime numbers besides 2 odd?
A prime number isn't divisible by anything by itself and 1. All even numbers are divisible by 2. Therefore, all prime numbers are odd.
Are all numbers divisible by both 4 and 6 also divisible by 24?
Yes.
All numbers divisible by 8 and 12 are also divisible by?
All numbers that are divisible by 8 and 12 would also be divisible by 4.
All even numbers are divisible by?
Two. All numbers are also divisible by 1.
Are all numbers divisible by 3 also by 9 give example?
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.
