**
13,860**.

### What is the LCM of 11 22 and 10?

110. LCM is "Least common multiple," meaning the smallest number divisible by each of the arguments. 110/11=10, 110/10=11, 110/22=5 implies 10, 11, and 22 all divide 110. 110 is the smallest such number because its prime factorization is 2*5*11. 2 and 5 are necessary because 10 must divide the answer; likewise 11 because 11 must divide the answer (remember 11 is prime).

### What is the smallest number that can be divided by 2 or 5 or 9 without leaving any remainder?

The required number is 90. The values produced by dividing 90 by 2, 3, 5, 7, and 11, the five smallest prime numbers, do not satisfy all the requirements: 90/2 = 45, which is not evenly divisible by 2; 90/3 = 30, which is not evenly divisible by 9; 90/5 = 18, which is not evenly divisible by 5; and the quotient of 90 and either 7 or 11 is not an integer itself.

### Is 209 prime or composite?

The number 209 is a composite number because it is divisible by 11 . A prime number is a number that can only be divisible by the number 1 and itself. But the number 209 is not only divisible by 1 and itself. It is also divisible by 11 and 19. So the number 209 is a composite number. 209 is a Composite Number

### What are the divisibility rules for 1-13?

0: Every number is divisible by 0 1: Every number is divisible by 1 2: Every even number is divisible by 2 3: If the sum of the digits is divisible by 3, then so is the whole number. Repeat the process if necessary - example: is 4,962 divisible by 3? 4+9+6+2=21 2+1=3 - 3 is divisible by 3. Therefore, 4,962 is also divisible by 3 4: If the last 2 digits of a number…

### How do you tell if a number is prime or not?

A prime number is one that has only two factors: one and itself. You can tell if a number is prime quickly by using the Laws of Divisibility: Numbers that end in 0, 2, 4, 6, and 8 are divisible by 2. If the sum of a number's digit is divisible by 3, the number itself is divisible by 3. If the last two digits of a number are divisible by 4, the number itself…

### 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 5278 divisible by3?

Add up the digits---5+2+7+8 22 which is NOT a multiple of 3 so it is NOT divisible by 3. == Here is a list of the divisibility rules: 2 If the last digit is even, the number is divisible by 2. 3 If the sum of the digits is divisible by 3, the number is also. 4 If the last two digits form a number divisible by 4, the number is also. 5 If the…

### Is the number 1859 a prime number?

To find out if 1859 is a prime number, use the rules of division: 1859 is not an even number, so it is not divisible by 2. The digits of 1859 add up to a number that is divisible by 3, so it is not divisible by 3. The last two digits (59) is not divisible by 4, so neither is 1859. The last digit is not 5, so it is not divisible by 5…

### What is the smallest number that has 5 different prime factors?

To calculate this interesting number you need to use the five smallest prime numbers. A prime number is one which is not evenly divisible by any other number (except itself and 1). The first prime number is 2. then we have 3, 5, 7, 11, 13, 17 and so on. So, if you multiply 2 x 3 x 5 x 7 x 11 you'll get the smallest number with 5 different prime factors.
