When is the LCM of two numbers equal to the product of the two numbers?
When the two numbers are coprime. Coprime numbers need not be prime numbers - they must not have any factor in common (other than 1). So, for eaxmple, neither 8 nor 9 are prime numbers but they are coprime and so, LCM(8 , 9) = 72
Is 415 and 30are coprime?
No because they are both composite numbers having more than two factors
How can you determine whether the LCM of two numbers is the product of the numbers or is less than the product if the numbers?
By finding out whether they have any factors in common. If the only factor they have in common is 1, the LCM will be their product. If they have more factors in common, their LCM will be less than their product.
When is a rational expression written in its simplest form?
When the numerator and denominator are coprime - ie have no factor in common other than 1.
What is a coprime?
In mathematics, two integers a and b are said to be coprime or relatively prime if they have no common positive factor other than 1 or, equivalently, if their greatest common divisor is 1. The notation a bis sometimes used to indicate that a and b are relatively prime. Extracted from Wikipedia.
How many numbers are co-prime to 3230 and less it?
1152 numbers are coprime with 3230 and smaller than it.
What are joint prime numbers?
Joint prime numbers, or coprimes, as they are better known, are numbers which do not share any factor in common (other than 1). The numbers may not themselves be prime. Any pair of successive integers must be coprime even if one or both of them may be composite. For example, 15 and 16.
What is a co-prime number?
There is no such thing as a coprime number.Two integers are said to be relatively prime (or coprime) if they have no common positive factor, other than 1. Examples:Any two different prime numbers are coprime.16 and 27 are coprime.14 and 18 are not coprime. They have the common factor 2.
Are 15 and 24 relatively prime?
No, coprime numbers have no common factors other than one; 15 and 24 both have the factor 3, so they are not coprime.
Two numbers are said to be coprime if they do not have a common factor other than 1 they are?
Another term for co-prime is relatively prime.
Is 32 the gcf of what 2 numbers?
Take any two coprime number, p and q. Coprime means that p and q do not share any common factor (other than 1). Then, 32p and 32q have a GCF of 32.
Is 13 and 52 coprime?
Oh, what a happy little question! When two numbers are coprime, it means they share no common factors other than 1. In this case, 13 and 52 are not coprime because they share a common factor of 13. But don't worry, every number has its place in the grand design of mathematics!
What are the coprime between 1 to 100?
Any integer greater than one can be co-prime.
What are coprime between 1 to 100?
Any integer greater than one can be co-prime.

Is one relatively prime with any number?
Yes. 1 is coprime to every integer greater than it.
Is it co-prime-15 and 25?
No. Since they have a common factor that is greater than 1 they cannot be coprime.
