Is the first number divisible by the second?
Sometimes.
A number is divisible by another number when the what is zero?
The second number must be non-zero for the division to be defined.For the concept of divisibility to make sense the second number must be an integer.Then, the first number is divisible by the secondwhen the first number, modulo the second, is zero,or equivalently,when the remainder of the division of the first number by the second is zero.
What is the smallest number divisible by 4 prime numbers?
The smallest number divisible by first four prime numbers is 2x3x5x7 = 210.
What is the smallest number divisible by the first three prime numbers?
The first three prime numbers are 2,3,5. The smallest number divisible by 2,3 and 5 is 30 (2*3*5).
What is a 4-digit number between 5200 and 5300 that is divisible by 10 and 11?
Ok think about it this way what options do you have? 5210 5220 5230 5240 5250 5260 5270 5280 5290 Which of those can be divided by 11? Only 5280. The reason is that you know that the starting number of the range is divisible by 10 so you can continue the pattern to generate this valid list for the first number. Once you have the list you can just check to see which number is divisible by your second number.
A number is said to be by a second number if the second number is a factor of the first number?
divisible
If the first number is multiplied by 3 the result is divisible by 6 Can the second number be an odd number?
If the second number is divisible by 6 then neither first nor second number is odd.
Whats it called when second number is a factor of the first number?

Is the factors of a number an divisible by a number the same thing?
Yes. If a number is divisible by another number, that second number is a factor of the first. 6 is divisible by 2, 2 is a factor of 6.
What do we call a number which is divisible by a given number?
IF they are integers, then the first number is a multiple of the second and the second is a factor of the first.
Is 4 divisible by 7321694?
No; as 4 is less than 7321694 it cannot be divisible by it. Nor is 7321694 divisible by 4. There are two tests for divisibility by 4 that I can offer. First (test given in most books): If the last two digits of the number (as a number) are divisible by 4 then so is the original number. Second (much easier test): add twice the tens digit to the ones digit; if this sum is divisible by 4 then so is the original number. Using second test, for 7321694: 2x9 + 4 = 22 which is not divisible by 4, so 7321694 is not divisible by 4. The second test can be repeated until a single digit remains; if this single digit is 4 or 8, then the original number is divisible by 4. otherwise not: 7321694 → 2x9 + 4 = 22 22 → 2x2 + 2 = 6 → not 4 or 8, so original number is not divisible by 4.
Is it true that all numbers are divisible by 3?
All numbers are not divisible by 3. In order to test if a number is a prime, you first test to see if it ends in a 2, 4, 6, 8, or 0. In that case it is divisible by 2 and not a prime. The next number you use for your test is 3. More odd numbers are divisible by 3 than by any other odd number but it is only the second number used for the test. You continue testing until you reach the square root of the number. If the number is only divisible by itself and one, it is prime. 3 is only the second test number in the division test for primes.
What Number is divisible by 2?
The numbers that are divisible by two are infinite. The first four are: 2,4,6,8 . . .
What is the one 9 digit delectable number which can be made using the digits 1 to 9?
A delectable number has nine digits, using the numbers 1-9 once in each digit. The first digit of a delectable number must be divisible by one. The first and second digits must be divisible by two, the first through third must be divisible by three, etc. There has only been one delectable number discovered: 381654729.
What is the converse of the contrapositive of a statement?
Look at the statement If 9 is an odd number, then 9 is divisible by 2. The first part is true and second part is false so logically the statement is false. The contrapositive is: If 9 is not divisible by 2, then 9 is not an odd number. The first part is true, the second part is false so the statement is true. Now the converse of the contrapositive If 9 is not an odd number, then 9 is not divisible by two. The first part is false and the second part is true so it is false. The original statement is if p then q,the contrapositive is if not q then not p and the converse of that is if not p then not q
