The other factors could be 4 and 5 or 1 and 20.
If the two numbers have no common factors other than 1, the LCM will be their product. If there are other common factors, the LCM will be less.
Square numbers have an odd number of factors.
If the two numbers have no common prime factors, the LCM will be the product of the numbers.
Two numbers are factors of a product when they multiply with each other to become the product. For example, if the product number is 10, then our factors can be 2 and 5, or 1 and 10.
No 9 is not prime. It's factors are 1,3,9. Proper factors: 1,3. Factors are numbers that are multiplied with other numbers to get a product. Proper factors are factors of a number except for itself. No 9 is not prime. It's factors are 1,3,9. Proper factors: 1,3. Factors are numbers that are multiplied with other numbers to get a product. Proper factors are factors of a number except for itself. Composite numbers are numbers with more than 2 factors and more than 1 proper factor. Prime is the opposite of composite.
If they have no common factors other than 1.
When one of them divides evenly into the product with no remainder and the result is the other number.
The LCM of two numbers is one of the numbers when one of the numbers is a multiple of the other. The LCM of two numbers is the product of the numbers when they are relatively prime. In all other cases (like consecutive even numbers that aren't 2 and 4) the LCM is as you describe.
If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.
Yes, if they have no common factors other than one.
There are no real numbers with the sum of 4 and a product of -477. The factors of -477 are (1,-477), (3, -159) and (9, -53). The negatives can be switched to the other numbers in those pairs of factors.
If the two numbers do not have any factors in common (other than 1), then the LCM is the same as the product of the two numbers. Example: LCM of 5 & 6 is 30, which is the same as the product.
