The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. If you have only one number - whether or not it is a prime - you cannot have a least COMMON multiple.

What is the LCM for 14 and 7?
The Least Common Multiple (LCM) of 7 and 14 is 14.
What is least common multiple of 11 and 12?
The least common multiple (LCM) of 11 and 12 is actually 11x12 = 132 This is because 11 is a prime number so has no common factors with 12
Is the LCM of a prime number and a composite number a multiple of the prime number?
If the GCF of two numbers is 1, their LCM will be their product. Such numbers are called relatively prime, or co-prime. Any two prime numbers (like 3 and 5) will be that way, but the numbers don't have to be prime (like 4 and 9).
What is the least common multiple of 11 28 2?
Since 11 is a prime number and does not evenly go into 28 or 2, then the least and only common denominator is 1.
What is the least common multiple of 840 and 1400?
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 1050 and 1400 is 4200.
What is the least common multiple of 5 and 12?
The least common multiple (LCM) of 5 and 12 is 60.
Can the greatest common factor and the least common multiple have the same number in prime factorization?
Only if they're the same number.
What is the LCM of 12 4 and 7?
The least common multiple (LCM) of 4,7, and 12 is 84.There is no least common multiple for those numbers: the number seven is a prime number.
What is the least common multiple of 11?
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.
What is the least common multiple of 13 and 8?
13 is a prime number. It and 8 have no factors in common. Therefore, the least common multiple is 8 x 13 = 104.
What is the least common multiple of two different prime numbers?
The least common multiple of two different prime numbers is the product of those two prime numbers.
What is the least common multiple of 130 using prime factorization?
There is not a least common multiple of a single number, such as 130, 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.
What is the least common multiple of 13 and 40?
520. 13 is a prime number and not a factor of 40.
What method would be useful to find the Least common multiple of a group of four number?
Prime factorization.
What has prime faccorisation got to do with least common multiple and greatest common factor?
Prime factorization tells you what prime numbers multiply to get the number. You can see which numbers that number is divisible by to get the multiples and factors.
What is the least common multiple of 8 and 16?
The least common multiple of 16 and 8 is 16. Because 16 is a multiple of 8, it is automatically the LCM of the pair. Another approach: To find the least common multiple, factor each number to its prime factors and then multiply all the factors from the first number with any factors in the second number that are not repeated from the first number. The prime factors of 8 are 2 x 2 x 2. The prime factors of 16 are 2 x 2 x 2 x 2.
What is the least common multiple of 18 27 and 35?
The least common multiple of 18, 27, and 35 is 1890, which is the multiple of the highest power of prime factors in the given numbers (2 x 3^3 x 5 x 7).
