Answer 2

Answer:

Required HCF is 2.

Step-by-step explanation:

Here given numbers are 64,74,84.

Here we want to find HCF of these given numbers.

But now question is How can we find HCF?

HCF means Highest Common Factor.

By one example we can understand this concept easily,

Take two numbers 20 and 25.

For HCF, first we need to break these numbers into prime numbers.

$20 = 2 \times 2 \times 5 \\ 25 = 5 \times 5$

Here highest common factor of 20 and 25 is 5.

So HCF of 20 and 25 is 5.

Here given numbers are 64,74,84.

First we are breaking 64,74,84 into prime numbers.

$64 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \\ 74 = 2 \times 37 \\ 84 = 2 \times 2 \times 3 \times 7$

Here highest common factor of 64,74,84 is 2.

So HCF of 64,74,84 is 2.
