The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you find sets of two numbers if HCF and LCM are known?

You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.


If the product oftwo numbers is 810 if there HCF IS 9 FIND LCM?

if the product of two numbers is 810 if there hcf is 9 find Lcm


If 13 is HCF of 2 number whose product is 1690 find the LCM?

To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get: 1690/13 = 130 And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.


Can the HCF of two numbers be a factor of their LCM?

The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.


If the HCF and LCM of two numbers are 17 and 102 respectively and the HCF and LCM of two other numbers are 68 and 476 respectively then find the sum of the HCF and LCM of these four numbers?

HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .


If LCM and HCF is known of 2 number along with 1 number can you find second number?

Yes: product of a & b = LCM x HCF so b = (LCM x HCF)/a


What are the four methods to find LCM and HCF?

hcf or gcf. first write the numbers the number can be multiplied to get it,you will have more than one or two numbers and when you see you have the number in a row then look for the highest number in all row .LCM do same as hcf but the numbers you got just multiply.try 2,4,16,24,48 you must get for LCM get 144 and for hcf or gcf you must get 24.


How do you find HCF if Lcm is 108?

Divide the product of the original numbers by 108, the LCM. The result will be the GCF.


The Product of two numbers is 1320 and their HCF is 6 Find the LCM of these two numbers?

220


What is the least common multiple of x and 6x?

To find the LCM of two numbers, you first need to find the HCF. In this case, the HCF is clearly x. Next you multiply the numbers together and divide by the HCF. x(6x)/x = 6x. Therefore the LCM of x and 6x is 6x.


Product of two numbers is 20736 and their HCF is 54 Find the LCM?

Can you always find the LCM by multiplying the numbers and dividing by HCF find an example where this does not work?

This does not work when one of the numbers is negative.


The LCM of two numbers is twice their HCF?

5 and 10 lcm- 10 and hcf= 5


What is the HCF and LCM of the numbers 526 and 213?

hcf: 1 lcm: 112,038


Can two numbers have 16 as their HCF and 380 as their LCM?

LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.


What numbers have a HCF of 3 and a LCM of 3?

Two or more numbers are needed to solve for HCF or LCM.


What is the LCM and HCF of 120?

You need at least two numbers to find both of those.


How would you explain the LCM of the two numbers is their product?

The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.


What is the lcm of 1 and 3?

To find the LCM of two numbers, you multiply them together and divide by the HCF. In this case one of the numbers is 1 and so the HCF can only be 1. Thus all we have to do is multiply the numbers together: 1x3 = 3 And therefore the LCM of 1 and 3 is 3.


What is tow LCM of 7 and 3?

To find the LCM of two numbers you need to multiply them together and then divide by the HCF. In this case, the numbers are coprime and so the HCF will be 1. Therefore was just have to multiply the numbers together: 7x3 = 21 And so the LCM of 7 and 3 is 21.


What is the HCF and LCM of 36 and 75?

To find the HCF you first have to write the numbers as their prime factors: 36 = 2x2x3x3 75 = 3x5x5 The next step is to identify any common prime factors. In this case both numbers have 3 as a prime factor. Thus the HCF is 3. To find the LCM you need to multiply the numbers together and divide by the HCF. 36x75/3 = 900 Thus the LCM of 36 and 75 is 900.


The product of two numbers is 396 X 576 and their LCM is 6336 Find the HCF?

The GCF is 36.


Can HCF and LCM of two numbers be 27 and 288?

No. The LCM MUST be a multiple of the HCF.


Does the HCF of any two no is always a factor of their LCM?

If two numbers are expressed as ab and cb this is easier to work out. Assume that a and c have no common prime factors. Thus, the HCF of the two numbers will be b. The LCM is the two numbers multiplied by each other, divided by the HCF. So the LCM will be abc. b is a factor of abc, and so the HCF will always be a factor of their LCM.


What is the LCM of 52 and 24?

To find the LCM you first have to express the numbers as the product of their prime factors: 52 = 2x2x13 24 = 2x2x2x3 The next step is to find the HCF. In this case, the HCF is 4. Finally, you multiply the numbers together and divide by the HCF: 52x24/4 = 312 And so the LCM of 52 and 24 is 312.
