Answer 1

Answer:

4

Step-by-step explanation:

8 = 2×2×2

100 = 2×2×5×5

Here, the highest common factor is 2×2 =4.

Answer 2

Answer:

$\large\boxed{4}$

Step-by-step explanation:

To find the highest common factor, first you have to use factors of 8 and 100. You can used greatest common factors like least common factors.

$\large\boxed{\textnormal{Highest Common Factor}}$

Given:

First, you have to find the prime factors of 8.

Solution:

$\displaystyle 2*2*2=8$

Next, you have to find the prime factors of 100.

$\displaystyle 5*5*2*2=100$

To find the highest common factor, make sure to multiply by prime factors from both numbers from left to right.

$\displaystyle 2*2=\boxed{4}$

Therefore, the highest common factor of 8 and 100 is 4.
