What is the fastest way to find the LCM trick?

How to Find the LCM – FAST!!!

1. Step 1) Find the GCF for the two numbers. For 18 and 30, GCF is 6.
2. Step 2) Divide that GCF into either number; it doesn’t matter which one you choose, so choose the one that’s easier to divide. Choose 18.
3. Step 3) Take that answer and multiply it by the other number.
4. Step 4) Celebrate …

How do you multiply LCM and HCF?

HCF and LCM of two numbers are related to each other as well as with the given numbers. For any two numbers a and b, HCF (a, b) × LCM (a, b) = a × b.

How do you do LCM and HCF in maths?

The formula that shows the relationship between their LCM and HCF is: LCM (a,b) × HCF (a,b) = a × b. For example, let us take two numbers 12 and 8. Let us use the formula: LCM (12,8) × HCF (12,8) = 12 × 8. The LCM of 12 and 8 is 24; and the HCF of 12 and 8 is 4.

What is HCF multiplied by LCM?

The product of HCF and LCM of any two given natural numbers is equal to the product of the given numbers. i.e.

Where do we use HCF and LCM?

What are Applications of LCM and HCF

1. To split things into smaller sections.
2. To equally distribute any number of sets of items into their largest grouping.
3. To figure out how many people we can invite.
4. To arrange something into rows or groups.

What is the use of HCF and LCM?

What are Applications of LCM and HCF. To split things into smaller sections. To equally distribute any number of sets of items into their largest grouping. To figure out how many people we can invite.

What are some shortcuts for HCF and LCM?

HCF and LCM Tips and Tricks and Shortcuts 1 The H.C.F of two or more numbers is smaller than or equal to the smallest number of given numbers 2 The smallest number which is exactly divisible by a, b and c is L.C.M of a, b, c. 3 The L.C.M of two or more numbers is greater than or equal to the greatest number of given numbers.

How to find the HCF of a number?

The factors of 4 are 2*2*1. Now, check whether the numbers are divisible by the factors. 18 and 22 are divisible by factor 2. Hence, the HCF is 2. Note: If there are more than two numbers, take the least difference. Question 5 Find LCM of 2,4,8,16.

How to find the HCF in the division method?

Division method to find the HCF (Shortcut method) 1 Larger number/ Smaller Number 2 The divisor of the above step / Remainder 3 The divisor of step 2 / remainder. Keep doing this step till R = 0 (Zero). 4 The last step’s divisor will be HCF.

Which is the shortcut method to find H.C.F?

The shortcut method to find both H.C.F. and L.C.M. is division method. Let us learn the relationship between HCF and LCM with the help of formula here. Also, we will solve some problems based on these two concepts to understand better.
