How do you do HCF problems?
How to find HCF by Prime Factorization?
- Step 1: Find the prime factors of the given numbers. In this case, the prime factors of 24 = 2 × 2 × 2 × 3, the prime factors of 36 = 2 × 2 × 3 × 3.
- Step 2: Multiply the prime factors that are common to both the numbers.
- Step 3: Therefore, the HCF of 24 and 36 is 12.
What is the LCM of 24 and 36?
72
LCM of 24 and 36 is 72. In Maths, the LCM of any two numbers is the value which is evenly divisible by the given two numbers. Least common multiple of 24 and 36 is the smallest number we get among the common multiples. (24, 48, 72, 96, ….)
How do you do HCF in maths?
Step 1: Divide the largest number by the smallest number. Step 2: Take divisor as new dividend and remainder as the new divisor, i.e. divide the first divisor by the first remainder. Step 3: Proceed till the remainder is zero and the last divisor will be the HCF of the given numbers. Therefore, HCF of 24 and 15 is 3.
How do you solve for HCF?
The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.
What is the LCM of 50 and 75?
150
The LCM of 50 and 75 is 150. To find the least common multiple of 50 and 75, we need to find the multiples of 50 and 75 (multiples of 50 = 50, 100, 150, 200; multiples of 75 = 75, 150, 225, 300) and choose the smallest multiple that is exactly divisible by 50 and 75, i.e., 150.
