Question

find the HCF of a. 225315 by factorization method and successive division method​

Answer 1

Answer:

Step I: 

Divide the large number by the smaller one. 

 

Step II: 

Then the remainder is treated as divisor and the divisor as dividend.

Step III: 

Divide the first divisor by the first remainder. 

Step IV: 

Divide the second divisor by the second remainder. 

Step V: 

Continue this process till the remainder becomes 0. 

Step VI: 

The divisor which does not leave a remainder is the H.C.F. or G.C.D. of the two numbers and thus, the last divisor is the required highest common factor (H.C.F) of the given numbers. 

Let us consider some of the examples to find highest common factor (H.C.F) by using division method.
