15 and 30 (among others) have an LCM of 30.


How do you find GCF knowing LCM?

The LCM of two numbers multiplied by their GCF will equal the product of the original numbers. If you know the LCM, divide it into the product. The result will be the GCF.


What is the relationship of the product to the product of gcf and LCM?

The product of two numbers is equal to the product of their LCM and GCF.


What two numbers have their LCM and GCF equal?

Any two, as long as they are the same number. The LCM and GCF of 10 and 10 is 10.

The product of the GCF and LCM of two numbers will equal the product of the two numbers.


Are the GCF and LCM of two numbers always equal?

Hardly ever.


Can the LCM of two numbers be equal to the smallest number in the set?

Never.


If the GCF of two numbers is 15 and their product is 300 what is their LCM?

The general rule is that the product of the LCM and the GCF is equal to the product of the original two numbers. That would make the answer 20. Lets overlook the fact that two numbers with a GCF of 15 and an LCM of 20 don't exist.

The product of the GCF and LCM of two numbers is equal to the product of the two numbers. The other number is 126.


How Given any two numbers which is greater the LCM of the numbers or. The GCF of the numbers why?

The LCM will never be less than the GCF. To be a multiple of both numbers, the LCM will have to be equal to or greater than the larger number. To be a factor of both numbers, the GCF will have to be equal to or less than the smaller number. The only problem comes when you're comparing a number to itself. The LCM of 10 and 10 is 10. The GCF of 10 and 10 is 10.


How can you determine from the prime factorization whether the least common multiple of two numbers is the product of the number?

If the two numbers have no common prime factors, the LCM will be the product of the numbers.


How do you check lcm answer?

One way to check: The product of the original two numbers is equal to the product of their GCF and LCM. If you divide that product by their GCF, you will get the LCM.
