How to work out hcf from prime factors

Web9 feb. 2024 · One good strategy is to try dividing the number by 2, then 3, then 5, working your way up through the prime numbers until you find one that divides evenly. Example: If you don't know any factors of 24, try dividing it by small prime numbers. Let's divide by 2 to get 24 = 2 x 12. We're not done yet, but this is a good start. Web26 jul. 2024 · Find the HCF and LCM of 24 and 180. Break the numbers into the product of prime factors using prime factor trees, as before. The product of prime factors for 24 are: \(2 \times 2 \times 2 \times 3\)

WebWe can use a process called prime factor decomposition using prime factor trees in order to work out the product of prime factors. E.g. Write 36 as a product of prime factors. 36 ÷ 2 = 18. 18 ÷ 2 = 9. 9 ÷ 3 = 3. So, 36 = 2 × 2 × 3 × 3. A question may ask you to give your answer in index form. WebFinding HCF & LCM with prime factorisations We want to find the HCF and LCM of the numbers 60 and 72. Start by writing each number as a product of its prime factors. 60 = 2 * 2 * 3 * 5 72 = 2 * 2 * 2 * 3 * 3 To make the next stage easier, we need to write these so that each new prime factor begins in the same place: thomas narkus tanzschule hamburg https://anywhoagency.com
