Question

Methods of finding the h.c.f​

Answer 1

Answer:

step 1: divide the largest number by the smallest number.

here, the largest number is 24 and the smaller one is 15. divide 24 by 15

prime factorization solution step 1

step 2: take divisor as new dividend and remainder as the new divisor, i.e. divide the first divisor by the first remainder.

prime factorization

step 3: proceed till the remainder is zero and the last divisor will be the hcf of the given numbers.

hcf

therefore, hcf of 24 and 15 is 3.

Answer 2

there are three methods of finding the h.c.f. of two or more numbers:

1)factorise method.

2)prime factorise method.

3) division method
