HCF of two or more numbers is the highest common factor of the given numbers. It is found by multiplying the common prime factors of the given numbers. Whereas the least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
How do you find the HCF of an activity?
Activity to find Cut one strip of length ‘a’ unit (say, a = 9 cm) and another strip of length ‘b’ unit (say, b = 5 cm) of width 1 cm each. Here, a > b. 3. Cut another strip of length ‘b’ unit (here, b = 5 cm) and another strip of length ‘c’ unit (here, c = 4 cm).
How to find the highest factor in HCF?
FACTORIZATION METHOD. In the hcf by factorization method,we find the greatest common factor by listing down the factors of the numbers. Step 1: List down the factors of all the given numbers. Step 2: Look for the highest factor among the listed factors which are common for both the given numbers. Let us take an example:
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.
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.
What are the properties of HCF of two numbers?
The properties of HCF are given below. HCF of two or more numbers divides each of the numbers without a remainder. HCF of two or more numbers is a factor of each of the numbers. HCF of two or more numbers is always less than or equal to each of the numbers. HCF of two or more prime numbers is 1 always.
