Question

find the HCF of 12,36,42?​

Answer 1

Answer:

6

Step-by-step explanation:

12,36,42

12 (divide with 3)       36 (divide with 3)         42     (divide with 3)

4  (divide with 2)        12 (divide with 3)          14     (divide with 2)

2  (divide with 2)        4  (divide with 2)         7       (divide with 7)

1                                  2  (divide with 2)         1

                                  1

12=3×2×2×1

36=3×3×2×2×1

42=3×2×7×1

HCF of 12,36,42  is=3×2=6

Answer 2

Answer:

The HCF of 12, 36, and 42​ is 6.

Step-by-step explanation:

Given: The numbers are 12, 36, and 42​.

We have to find the HCF of the above numbers.

• As we know, the HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers.
• HCF is also known as the greatest common factor.

We are solving in the following way:

We have,

The numbers are 12, 36, and 42​.

First, we will find the factors of the above numbers.

The factors of 12 are: $1, 2, 3, 4, 6, 12$

The factors of 36 are: $1, 2, 3, 4, 6, 9, 12, 18, 36$

The factors of 42 are: $1, 2, 3, 6, 7, 14, 21, 42$

 From the above, we can see that 6 is the highest number among all the common factors of the given numbers.

So, the greatest common factor(HCF) is 6.
