To determine if the first number is divisible by the second, you need to divide the first number by the second number. If the division result is a whole number without a remainder, then the first number is divisible by the second. For example, if the first number is 12 and the second number is 3, when you divide 12 by 3, the result is 4, which is a whole number, indicating that 12 is divisible by 3.
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.
The smallest number divisible by first four prime numbers is 2x3x5x7 = 210.
The third one.
The first three prime numbers are 2,3,5. The smallest number divisible by 2,3 and 5 is 30 (2*3*5).
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.
divisible
If the second number is divisible by 6 then neither first nor second number is odd.
The first number is divisible by the second number
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.
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.
IF they are integers, then the first number is a multiple of the second and the second is a factor of the first.
No, 6 is not divisible by 148. In order for one number to be divisible by another, the first number must be a multiple of the second number. In this case, 6 is not a multiple of 148 as it is much smaller. Therefore, 6 is not divisible by 148.
No, 3 is not divisible by 555. In order for a number to be divisible by another number, the remainder when dividing the first number by the second number must be zero. In this case, when dividing 3 by 555, the remainder is 3, indicating that 3 is not divisible by 555.
Depends on the number
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.
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.
The numbers that are divisible by two are infinite. The first four are: 2,4,6,8 . . .
