Question

the hcf of 480,920,630

Answer 1

Answer:

HCF (480,920,630) = 10

Step-by-step explanation:

Given,

To find the HCF, we need to find prime factorisation of the given number and take the common factor from each number to find out the highest common factorisation.

Prime factorisation of each no. is

480= 2*2*2*2*3*2*5

920= 2*2*2*5*23

630 = 2*5*3*7*3

HCF (480,920,630) = 2*5 = 10

Hence the HCF (480,920,630) = 10

Answer 2

Answer:

The HCF of the given numbers is 10.

Step-by-step explanation:

Given: The numbers are 480, 920, and 630.

We have to find the HCF of the above numbers.

• As we know that the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

We are solving in the following way:

We have,

The numbers are 480, 920, and 630.

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

The factors of 480 are:

$1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, \\80, 96, 120, 160, 240, 480$

The factors of 630 are:

$1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630$

The factors of 920 are: $1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920$

From the above, we can see that 10 is the largest positive integer that divides each of the integers.

Then the greatest common factor(HCF) is 10.

In this problem, we are assuming we have to find the HCF of the given numbers.
