The LCM of 15 and 30 is 30.
Similarly, What is the HCF 15 and 30?
Answer: The HCF of 15 and 30 is 15.
Additionally, How do you solve for LCM? One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

What is the HCF of 20?
The HCF of 20 and 30 is 10. To calculate the Highest common factor (HCF) of 20 and 30, we need to factor each number (factors of 20 = 1, 2, 4, 5, 10, 20; factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30) and choose the highest factor that exactly divides both 20 and 30, i.e., 10.
What is the HCF of 10 15 and 20?
As you can see when you list out the factors of each number, 5 is the greatest number that 10, 15, and 20 divides into.
What is the LCM of 15 and 20?
The smallest number to appear on both lists is 60, so 60 is the least common multiple of 15 and 20.
What is the easiest way to find the HCF of a large number?
Also, for finding the HCF of two numbers, we can also proceed by long division method. We divide the larger number by the smaller number (divisor). Now, we divide the divisor by the remainder obtained in the previous stage. We repeat the same procedure until we get zero as the remainder.
What is the HCF of 24 and 36 and 42?
The H.C.F. is 6.
How do you solve HCF problems?
Example 4: Find the greatest number, which when divides 41, 71 and 91, leaves the same remainder in each case. Sol: Take the difference between all the three pairs of numbers and their HCF will be the answer i.e. 91 – 41 = 50, 71 – 41 = 30 and 91 – 71 = 20. Now, the HCF of 50, 30 and 20 is 10.
What is the LCM and GCF of 8 and 12?
Example 2: Find the GCF of 8 and 12, if their LCM is 24. Therefore, the greatest common factor of 8 and 12 is 4. Example 3: For two numbers, GCF = 4 and LCM = 24. If one number is 8, find the other number.
