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.
What is the LCM and HCF of 12 and 20?
Answer: LCM of 12 and 20 is 60.
What is the GCF of 12 and 20 using continuous division?
The common factors of 12 and 20 are 1, 2 and 4. The greatest common factor of 12 and 20 is 4. To find the Greatest Common Factor (GCF) of two or more whole numbers, follow this procedure: Make a list of factors for each whole number.
How is the division method used in HCF?
Basically division method is nothing but dividing the given numbers simultaneously to get the common factors between them. Follow the steps mentioned below to solve problems of hcf. Step 1: Write the given numbers horizontally, in a sequence, by separating it with commas. Step 2: Find the smallest prime number which can divide the given number.
How is the HCF of two numbers determined?
We have already understood the prime factorisation method to determine the HCF. First, divide the large number by a small number. If the remainder is left, then divide the first divisor by remainder. If the remainder divides the first divisor completely, then it is the HCF or highest common factor of the given two numbers.
How to find the HCF of 120 and 100?
Solution: Now, let us find the HCF by using division method. Divide 120 by 100. Now, divide the first divisor 100 by first remainder 20. 100/20 → 5 and remainder is 0. Therefore, 20 is the HCF of 120 and 100. Question 2: Find the HCF of 45 and 60 by the division method. Solution: Divide 60 by 45.
Which is the best way to solve HCF problems?
Follow the steps mentioned below to solve problems of hcf. Step 1: Write the given numbers horizontally, in a sequence, by separating it with commas. Step 2: Find the smallest prime number which can divide the given number. It should exactly divide the given numbers. Step 3: Now write the quotients.
