Multiply the number by 1, 2, 3, 4 and so on.
If a number is a multiple of 5, it will be greater than 5 and end in a 5 or a zero.
Since 5 is a prime number, then any number, which is not a multiple of 5, is relatively prime with the number 5. You can determine if a number is a multiple of 5, by looking at the ones place digit. If it is a 0 or 5, and the number itself is not zero, then the number is a multiple of 5.
There are an infinite number of multiples of 6 (numbers that six can divide into evenly with no remainder). Without using a calculator, you can determine if a number is a multiple of 6. To be a multiple of 6, it must have both 3 and 2 as factors. So if the number is even, then 2 is a factor. To determine if it is even, look at the ones digit, and if it is (0,2,4,6, or 8) then it's even. Then to determine if 3 is a factor, add the digits in the number, if this sum is a multiple of 3, then the number is also a multiple of 3 (or you could say 3 is a factor). If both of these are true, then the number is a multiple of 6. Example: 984: Last digit (ones digit) is 4, so it's even. Sum 9+8+4=21, which is a multiple of 3, so the number is a multiple of 3. Therefore it is a multiple of 6.
Unfortunately, we will need that second number to determine an LCM.
No, 118 is not a multiple of 9. To determine if a number is a multiple of 9, you can sum its digits: 1 + 1 + 8 = 10. Since 10 is not divisible by 9, 118 is not a multiple of 9.
Two or more whole numbers are required to determine their least common multiple.
No, 4, 5, and 8 are not multiples of 40. A number is a multiple of another number if it can be divided evenly by that number. To determine if a number is a multiple of 40, you would need to see if it can be divided by 40 without a remainder.
If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7. or Divide 7 into it. If the answer has no remainder, the number is divisible by 7.
To determine if a number is a multiple of 3, we can add up the digits of the number. For 4036, we have 4+0+3+6 = 13. Since 13 is not divisible by 3, 4036 is not a multiple of 3.
To determine the probability of hitting a specific hand in poker when multiple runs are possible, you can use combinatorial mathematics to calculate the number of ways that hand can be achieved and divide it by the total number of possible outcomes. This will give you the probability of hitting that specific hand.
To determine if 522 is a multiple of 9, you can use the rule that a number is a multiple of 9 if the sum of its digits is a multiple of 9. The digits of 522 are 5, 2, and 2, which sum to 9. Since 9 is a multiple of 9, it follows that 522 is also a multiple of 9.
Divide the number of events that can happen a certain way by the number of all possible events.
