Take a number you'd hate to divide out longhand: 1,358,024,668.
Add its first digit to its third to its fifth etc. till there are no more: 1 + 5 + 0 + 4 + 6 = 16.
Repeat with the even digits: 3 + 8 + 2 + 6 + 8 = 27.
Subtract the larger number from the smaller. If the result is 11 or 0, your number is divisible by eleven, otherwise not. In this case, 27 - 16 = 11, so 1,358,024,668 IS divisible by eleven.
Oh, dude, let me put on my math hat for a sec. So, to find a number between 1100 and 1200 that's divisible by 11 and 13, we need to find the least common multiple of 11 and 13, which is 143. Then we just need to find which multiple of 143 falls within the given range. So, the number you're looking for is 1147. Boom, mathed it!
No.
11 is a prime number.
A multiple of 11
A multiple of 11 can't be a prime number.
You need at least two numbers to find an LCM.

1155 is obviously a multiple of 5 and a multiple of 11, so it is a composite number.
You can't find the Lowest Common Multiple (LCM) of only one number. You need at least two numbers to find the LCM.
The least common multiple (LCM) of 2, 11, and 5 is the smallest multiple that all three numbers share. To find the LCM, you first need to find the prime factors of each number: 2 = 2, 11 = 11, and 5 = 5. Then, you multiply the highest power of each prime factor to find the LCM: LCM(2, 11, 5) = 2 * 11 * 5 = 110. Therefore, the least common multiple of 2, 11, and 5 is 110.
A multiple of 11 can't be a prime number.
There is not a least common multiple of a single number, such as 11, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.Examples:The least common multiple of 3 and 11 is 33.The least common multiple of 11 and 77 is 77.The least common multiple of 2, 5, and 11 is 110.Note: Since 11 is a prime number, if the other number is not a multiple of 11, the least common multiple will be 11 times the other number.
The number that is a multiple of 2 and 11 at the
A single number cannot have a least common multiple because "common" refers to multiples that two or more numbers have in common. You have only one number.
