the greatest common factor 4,8 and 12 is _______ or else i will report brain list​

Answer 1

ANSWER:

The greatest common factor of 4,8 and 12 is 4.

$\rule{300}{2}$

EXPLANATION:

Here in this question concept of HCF (Highest Common Factor) is used. We have given certain numbers and we have to find Highest Common Factor. So let's expand the given numbers into product of their primes to find the common factors.

So let's start!

$\rule{300}{2}$

Prime factorisation:-

4=2×2

8=2×2×2

12=2×2×3

2×2 is common in all the three numbers.

2×2=4

$\rule{300}{2}$

Here we can see that 4 is common in all of the three numbers.

∵Hence it is the highest common factor.

$\rule{300}{2}$

ADDITIONAL INFORMATION:

Let us assume 2 numbers be x and y, what is the relationship between LCM, HCF, x and y?

★ LCM×HCF=Product of both numbers.

$\rule{300}{2}$
