The HCF of two or more numbers is the greatest number that divides each of them exactly. The LCM of two or more numbers is the smallest of the common multiples of those numbers. Learn more about how to find the HCF and LCM in this article.

To find the other number when the HCF (Highest Common Factor) and LCM (Lowest Common Multiple) of two numbers are given, along with one of the numbers, we can use the formula:HCF × LCM = First Number × Second NumberGiv
Let us use the above steps in the example given below: find the LCM of 15,30,90. Step 1: Rewrite the numbers in a row separated by commas. Step 2,3 and 4: Find the prime factors, the number with no quotients is written as it is. The step is repeated until we reach the stage...
What is the Relationship between HCF and LCM of two Numbers? The formula that expresses the relationship between the Least Common Multiple (LCM) and HCF is given as, LCM (a,b) × HCF (a,b) = a × b; where 'a' and 'b' are the two numbers. What is the HCF of two Consecutive ...
CAT HCF LCM - Theory There are three numbers a,b, c such that HCF (a, b) = l, HCF (b, c) = m and HCF (c, a) = n. HCF (l, m) = HCF (l, n) = HCF (n, m) = 1. Find LCM of a, b, c. (The answer can be "This cannot be determined"). ...
So, if the two bell toll together now, again they will toll together after 12 seconds. This 12 is the least common multiple (LCM) of 3 and 4. The same thing happened in our problem. To find the time, when they will all toll together, we have to find the LCM of (2, 4, 8, ...
Relation 1:The product of LCM and HCF of any two given numbers is equivalent to the product of the given numbers. LCM × HCF = Product of the Numbers Suppose P and Q are two numbers, then. LCM (P & Q) × HCF (P & Q) = P × Q ...
