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 highest common factor of 735 and 756?
HCF(735, 756) = 21 It can save you a lot of time if you use the fact that for any integers A and B, HCF(A, B) = HCF(A, B-A) That soon gives you small numbers to factorise.
Find HCF of 260 and 560?
HCF is the highest common factor of two or more numbers. HCf of 260 and 560 is 20.
What is the highest common factor of 30.210 and 700?
It is: 10 that is the HCF of 30, 210 and 700
What is the HCF of 99?
The HCF of 99 is 99. But it's a factor as opposed to a common factor because there's only one number.
Why do you factor numbers in algebra?
to find a factor of a number you have to 1. find the hcf (highest common factor) 2. find how many times the hcf goes into your number AND THAT IS YOUR ANSWER!
Can you find the HCF of 3 numbers using euclids division lemma?
Yes.First find the HCF of two of the numbers, then find the HCF of that answer and the third number.In this way you could find the HCF of as many numbers as you want.
What is Highest common factor (HCF) of 27?
Two or more numbers are needed to find their HCF
Find the HCF of 168 and 264?
The HCF (highest common factor) of 168 and 264 is 24

Why is the gcf of two even numbers are always even?
All even numbers have two as a factor. That means that any set of even numbers will have at least a two as a common factor. Since 2 will be a part of the greatest common factor, it will have to be even.
Find HCF of 260 and 560?
HCF is the highest common factor of two or more numbers. HCf of 260 and 560 is 20.
How do you do a quotient in simplest form?
Suppose you have a quotient in the form X/Y where X and Y are integers, and you wish to find the simplest form of X/Y. First find the highest common factor of X and Y. Suppose HCF(X, Y) = H Then calculate A = X/H and B = Y/H The simplest form is A/B. If you do not know what the HCF is or the HCF is too hard to find then just find any common factor, F. That is, any number that will divide both X and Y. Then a simpler equivalent of X/Y is (X/F)/(Y/F). Find another common factor and repeat. Keep going until you cannot find a common factor. Your last "simpler equivalent" is the answer.
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
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.
How do you find the quotient in simplest form?
Find the Highest Common Factor (HCF) of the numerator and denominator of the fraction. Divide both by their HCF and you will have the fraction in its simplest form.
