Question

hcf of 120,380,480=​

Answer 1

Step-by-step explanation:

first divide with 10

then 12,38,48

then divide with 2

then 6,19,24

19 is prime number we can't divide any thing

answer =20✓ is correct

Answer 2

Answer:

The HCF of$120,380,480 = 20$.

Step-by-step explanation:

Given: The numbers are$120,380,480$.

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$120,380,480$.

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

The factors of 120 are: $1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120$

The factors of 380 are: $1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380$

The factors of 480 are:

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

From the above, we can see that 20 is the largest positive integer that divides each of the integers.

Therefore the greatest common factor(HCF) is 20.

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