Question

HCF by common ,divison method (a) 24,180 and 260

Answer 1

Answer:

4 would be the hcf

Process-

1) take mutual difference which is less(260-180<180-24)

2) now either 80 or it's factors would be the hcf

check it,

now,

20 X 4 factors,

4 would be the hcf because it can divide all the numbers completely..

and also it's the highest factor..

Hint: First, before proceeding for this, we must know the following division is not the simple type of division as it is continuous division and will not stop until we get remainder as zero. Then, we get the HCF as 120 which is defined as the last divisor which makes the division remainder to be zero is called HCF(Highest Common Factor). Then, by using the above found HCF for the last remaining number which is 120, check whether it is fully divisible by it or not by performing long division again to get the final answer.

Complete step-by-step answer:

In this question, we are supposed to find the HCF of 180, 240 and 360 by long division method.

So, before proceeding for this , we must know the following division is not the simple type of division as it is continuous division and will not stop until we get remainder as zero.

So, by starting the two larger numbers which are 240 and 360 and then dividing them by long division method as:
