Since two primes obviously have no common factors greater than 1, you find the least common multiple by multiplying them together. This is true for any pair of numbers with no common factors greater than 1., not just prime numbers.
Two numbers with no common factors greater than one are called relatively prime. For example, 8 and 9 are relatively prime even though both are composite numbers.
The least common multiple of two different prime numbers is the product of those two prime numbers.
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
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.
Prime numbers or relatively prime numbers.
When they have no common prime factors.
It depends on what the numbers are. For example, if the prime numbers you were talking about were 3 and 7, the least common multiple would be 21. If your numbers were 2 and 3, it would be 6.
The least common multiple of two numbers is the product of those two numbers, divided by the greatest common factor of those two numbers. Two numbers that are relatively prime have a greatest common factor of 1. So, when the two numbers are relatively prime, the least common multiple is the product of both numbers divided by 1. So, when two numbers are relatively prime, the least common multiple is the product of the two numbers.this is wron
The Least Common Multiple of 48, 72 is 144.
The least common factor of any set of positive integers is 1. The least common multiple of relatively prime numbers is their product.
3 and 17
The greatest common multiple is an infinite amount and not very practical for problem solving. The least common multiple of two prime numbers is their product.
The LCM of prime numbers is simply their product (a x b, or x*y). The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of two prime numbers is 1. Therefore, the least common multiple of two prime numbers is the two numbers multiplied together, since dividing by 1 will not change the answer. The same applies to "relatively prime" numbers such as 10 and 21, where the GCF is also 1.
They are relatively prime, or co-prime.
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.
31 and 5 are prime numbers.
By finding their prime factors
If the prime factorizations have no factors in common, the LCM is the product of them.
The least common multiple of 7 and 13 is 91. Because the numbers in the set are prime, their LCM is their product.
Any pair of prime or relatively prime numbers.
When the two numbers have no common factors. This is called relatively prime.
