The product of two number is 20736 and their HCF is 54 find the LCM?

LCM = Product/HCF = 384


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.


What two number have an LCM of 30 and an HCF of 3?

30 and 3.


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

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


The LCM of two numbers is twice their HCF?

5 and 10 lcm- 10 and hcf= 5


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.


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.


The ratio of two number is 34 and their HCF is 4.ewhat will be their LCM?

48


Which 2 nos have same LCM and HCF?

Any two of the same number. The GCF and LCM of 10 and 10 is 10.


How will I find a number when the LCM is 252 and HCF is 14 and the first number is 28?

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 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 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 .


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

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


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.


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 relation between HCF and LCM?

Since the product of two numbers is equal to the product of their GCF and LCM, the GCF of two numbers is equal to their product divided by their LCM and their LCM is equal to their product divided by their GCF.


The HCF of two numbers is 4 and their LCM is 576 If one of the numbers is 64 find the other number?

I have been preparing for my GRE and have been practicing similar questions from www.examville.com The other number = HCF * LCM / Given number = 4 * 576 / 64 = 36


What do HCF and LCM stand for?

HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.


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


Why is the LCM of 12 and 13 the same as there product but the LCM of 12 and 14 is not the same as there product?

The LCM is the product of the two numbers divided by their HCF. With 12 and 13, the HCF is 1. Therefore, the LCM will equal the product. With 12 and 14, the HCF is 2. Therefore, the LCM will be half of the product.


What is HCF and LCM of 70?

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


What is the relationship between HCF and LCM?

It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.


Which two numbers have an LCM of 60 and HCF of 5?

4


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.


What is the LCM of 64 and 610?

LCM of two numbers = their product divided by their HCF. The HCF of 64 and 610 is only 2 so the LCM is 64 x 610/2 ie 19520.
