Std- 6 class​

Answer 1

Answer:

HCF of 45 and 30 is 15

Step-by-step explanation:

Method 1:

Factors of 45: 1, 3, 5, 9, 15, 45

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

There are 4 common factors of 45 and 30, that are 1, 3, 5, and 15. Therefore, the highest common factor of 45 and 30 is 15.

Method 2:

45 = 3 × 3 × 5

30 = 3 × 2 × 5

So, common = 3 × 5 = 15

The HCF of 45 and 30 is 15.

Answer 2

Answer:

As a result, the HCF values of 45,30 are$=15$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question HCF 45,30

We have find the HCF 45,30

We know that the HCF full form is  highest common factor

So as we get

HCF= 45,30

1 The prime factor of 45 are $3,3$ and $5$

2,The prime factor of 30 are $2 ,3$ and 5

So, common factor is $3$ and 5

So HCF 45,30 are

$3\times 5\\15$

As a result, the HCF values of 45,30 are$=15$
