What is the LCM of 22 and 66?
To sum up, the lcm of 22 and 66 is 66. In common notation: lcm (22,66) = 66.
Which is the highest HCF of 24 and 36?
Similarly, HCF of 24 and 36 is 12, because the common factors of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12. Hence, the Highest Common Factor (H.C.F) of 24 and 36 is 12 and for 24, 36 and 56 it is 4. Hence, 2 is the Highest Common Factor of 18, 20 and 12.
Which is the highest HCF of 60 and 75?
For example: highest common factor of 60 and 75 = 15 because 15 is the highest number which divides both 60 and 75 exactly. Similarly, HCF of 24 and 36 is 12, because the common factors of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12.
How to find HCF of more than 3 numbers?
3) The HCF you got in step 2 will be the HCF of the 3 numbers. The above steps can also be used to find the HCF of more than 3 numbers. Here is a few more example to find the highest common factors. Example 1: Find out HCF of 30 and 45. So, the HCF of 30 and 45 is 15. Example 2: Find out HCF of 12 and 36.
Which is the highest common factor in HCF?
As we can note that the mentioned prime factors, on the left side, divide all the numbers exactly. So, they all are common prime factors. We have no common prime factor for the numbers remained at the bottom. So, HCF = 3 × 5 = 15. HCF = 2 × 2 × 3 = 12. Example 3: Find out HCF of 36, 12, 24 and 48. HCF = 2 × 2 × 3 = 12.
