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.
No.
11 is a prime number.
A multiple of 11
A multiple of 11 can't be a prime number.
No, since 11 is less than 44 it can not be a multiple, as it is defined (basically) as a number achievable by multiplying the base number by some integer. e.x.: 22 is a multiple of 11 ( 11 x 2 = 22 ). 44 is a multiple of 11 ( 11 x 4 = 44 ). 11 is not a multiple of 44 ( 44 x 1/4 = 11) since 1/4 is not an integer.
You need at least two numbers to find an LCM.
No.
11 is a prime number.
A multiple of 11
1155 is obviously a multiple of 5 and a multiple of 11, so it is a composite number.
A multiple of 11 can't be a prime number.
You can't find the Lowest Common Multiple (LCM) of only one number. You need at least two numbers to find the LCM.
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 least common multiple of 11 and 22 is 22.
No, since 11 is less than 44 it can not be a multiple, as it is defined (basically) as a number achievable by multiplying the base number by some integer. e.x.: 22 is a multiple of 11 ( 11 x 2 = 22 ). 44 is a multiple of 11 ( 11 x 4 = 44 ). 11 is not a multiple of 44 ( 44 x 1/4 = 11) since 1/4 is not an integer.
A multiple of a number is something you get when you multiply that number by another. For instance, 5 x 2 = 10, so 10 is a MULTIPLE of 5 and a MULTIPLE of 2. If you're trying to find a multiple of a number, say, 3, multiply that number by another. It can be any number.
There is no Greatest Common Multiple for whatever number you come up with I can always add another 22 (the LowestCommon Multiple (lcm) of 11 and 2) and get another higher number still a multiple of both 11 and 2.
