Question

how to do HCF plz tell plz tell

Answer 1

H.C.F. by Long Division Method:-
To find the H.C.F. of the given number we will follow the following steps:

1.We divide the bigger number by smaller one.
2. Divide smaller number in step 1 with remainder obtained in step 1.
3. Divide divisor of second step with remainder obtained in step 2.
4. We will continue this process till we get remainder zero and divisor obtained in end is the required H.C.F.

Answer 2

Answer:

Step-by-step explanation:

The H.C.F. of two or more than two numbers is the greatest number that divides each of them exactly.

There are two methods of finding the H.C.F. of a given set of numbers:

Factorization Method: Express the each one of the given numbers as the product of prime factors. The product of least powers of common prime factors gives H.C.F.

Division Method: Suppose we have to find the H.C.F. of two given numbers, divide the larger by the smaller one. Now, divide the divisor by the remainder. Repeat the process of dividing the preceding number by the remainder last obtained till zero is obtained as remainder. The last divisor is required H.C.F.

Finding the H.C.F. of more than two numbers: Suppose we have to find the H.C.F. of three numbers, then, H.C.F. of [(H.C.F. of any two) and (the third number)] gives the H.C.F. of three given number.

Similarly, the H.C.F. of more than three numbers may be obtained.
