Hcf multiplied by lcm
WebMay 19, 2016 · Any multiple of 715 must have factors of 5, 11 and 13. So, 825 should be multiplied by the factor (s) of 715, which is (are) not present in 825. ∴ The required least number = 13. Question 3. The LCM of two numbers is 2310 and their HCF is 30. If one of the numbers is 7 × 30, find the other number. Solution: the required number = (2310 ×30 ... WebNov 24, 2024 · HCF. The full form of HCF is the highest common factor – It is the largest possible number that can divide each of the numbers in a group without leaving a reminder. In other words, all the numbers in the group can be exactly divided by HCF. For example, the HCF of 12 and 6 is 6. The numbers 12 and 6 have common divisors 1,2,3 and 6.

WebThe Least Common Multiple ( LCM) is also referred to as the Lowest Common Multiple ( LCM) and Least Common Divisor ( LCD). For two integers a and b, denoted LCM (a,b), the LCM is the smallest positive … WebLCM means the lowest common multiple. Since division of integers such as 0 is UNDEFINED. That is because you can only do LCM if the numbers "a" and "b" are numbers other than 0. Otherwise the whole problem is UNDEFINED. But even If you asked the LCM of 0 and 5, It would be undefined and would be 0 itself. Hope this answer helped 👍
WebHCF and LCM formulae: • The product of LCM and HCF of any two respective natural numbers is equal to the product of the given numbers. LCM × HCF = Product of the numbers (applicable for two numbers) Suppose X and Y are two numbers, then LCM (X and Y) × HCF (X and Y) = X × Y WebQ1) What are HCF and LCM?

WebUsing the HCF and LCM formula, we can find the unknown value. HCF (a, b) × LCM (a, b) = a × b After substituting the values we get, 8 × 96 = 24 × b So the value of 'b' = 768/24 = 32. Therefore, the other number is 32. Note: Similarly, we can find the LCM of two numbers if we know the two numbers and the HCF using the same formula. WebWhat is HCF and LCM?

WebMay 1, 2024 · HOW TO: FIND THE LCM USING THE PRIME FACTORS METHOD Step 1. Find the prime factorization of each number. Step 2. Write each number as a product of primes, matching primes vertically when possible. Step 3. Bring down the primes in each column. Step 4. Multiply the factors to get the LCM. Example 2.10. 6: lcm
WebFeb 25, 2012 · In this case we have: 30 = 2x3x5. 45 = 3x3x5. The next step is to identify any common factors. In this case both numbers have 3 and 5 as prime factors. To find the HCF, multiply these together: 3x5 = 15. To get the LCM, multiply the numbers together then divide by the HCF: 30x45/15 = 90.
