Question

what is the HCF of 120 150 240..​

Answer 1

Given:

120 150 240

According to the question we have to find the HCF of all the values

For find the HCF first we find the factors of all the values

Here factors of first value are:

120 = 2 ×2 ×2 ×3 × 5

Factors of 150 are:

150 = 2 ×3 ×5 ×5

Factors of 240 are :

240 = 2 ×2 ×2 ×2 ×3 ×5

The common factors are 2  × 3 × 5

HCF = 2 × 3 × 5 =30

Hence the HCF of all the values are 30

Answer 2

Here, it is given that,

$120, 150, 240$

To find the HCF of the given numbers

For that we have to find the factors,

$=>120=2\times 2\times2\times3\times5\\=>150=2\times3\times5\times5\\=>240=2\times2\times2\times2\times3\times5$

From above factors the common factor we get,

$=>2\times3\times5$

So, the HCF $=2\times3\times5=30$

Hence, the HCF of $120, 150, 240$ is $30.$
