Question

What is the HCF of 16and40​

Answer 1

Answer:

40 divided by 8 is 5. Neither of these can be reduced by any more common numbers, so therefore, 8 is your greatest common factor. The HCF of 16 and 40 is 8

Step-by-step explanation:

Answer 2

Here it is given that,

$16$ and $40$

We have to find the HCF of the given numbers,

First, we need to know the prime factors of the given numbers,

The prime factors of $16$ are 2, 2, 2, and 2.

The prime factors of $40$ are 2, 2, 2 and 5.

Identifying the common prime factors,

As the common prime factors are 2, 2 and 2

Now, we have to calculate the GCF,

The product of the prime factors that all of the original numbers have in common is the greatest common factor.

GCF = $2\times 2\times2$

GCF = $2^3$

GCF = 8

The greatest common factor of $16$ and $40$ is 8.
