What pair of numbers have a LCM is 75 and GCF is 5?

5 and 75 15 and 25


How do you work out which 2 numbers have an lcm of 30 and an HCF of 3?

In these types of problems, the numbers can also be the answer. 3 and 30 have a GCF of 3 and an LCM of 30. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 90, like 6 and 15.


What is the gcf and the LCM for the numbers 15 and 60?

15 and 60, respectively.


What is 2 number pairs have a LCM of the number 60?

This doesn't work. The LCM of a pair of numbers has to be equal to or larger than the largest number of the pair. If one of the numbers is 60, the other is 120. 60 and 120 have a GCF of 60, not an LCM.


How do you Find a pair of numbers whose LCM is 75 and whose GCF is 5?

75 = 3*5*5, so the first pair that comes to mind is 3*5 and 5*5.LCM(15, 25) = 75.And it conveniently happens to be that GCD*(15, 25) = 5.So {15, 25} is the answer (at least an answer).*GCD is "Greatest Common Divisor" and a more official way of saying GCF.* * * * *Yes, it is an answer.Consider LCM/GCF = 75/5 = 15If p and q are any two coprime factors of LCM/GCF = 15, then p*GCF and q*GCF will be an answer.The above answer used p = 3 and q = 5.The other possible pair is p = 1 and q = 15 which gives the pair as 5 and 75.


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.


What is the product of two numbers is 2700 their GCF is 15 what is the LCM?

Their LCM is 2700/(15^2) = 180.
