# Help with mathematics (numbers and variables)

Hello :D I have a question, I have gotten home as a homework and I looking someone help who саn do my homework because don't quite understand how this works:

Break the following numbers into the product of their prime factors: 252, 882, 4000 and then:

Find the largest common divisor of 18.24 45, 54, 90
and last but not least:

Determine the least common multiple of
24, 56, 168
12, 18, 60
35, 49, 567

I know it's pretty much ... but I can not keep up on this topic: // well, thanks in advance :) Note by Daisy Rowley

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Remember to wrap math in $$ ... $$ or $ ... $ to ensure proper formatting.
2 \times 3 $2 \times 3$
2^{34} $2^{34}$
a_{i-1} $a_{i-1}$
\frac{2}{3} $\frac{2}{3}$
\sqrt{2} $\sqrt{2}$
\sum_{i=1}^3 $\sum_{i=1}^3$

Sort by:

1) $252 = 2^2 \times 3^2 \times 7$

$882 = 2 \times 3^2 \times 7^2$

$4000 = 2^5 \times 5^2$

2) $18 = 2 \times 3 \times 3$

$24 = 2 \times 2 \times 2 \times 3$

$45 = 3 \times 3 \times 5$

$54 = 2 \times 3 \times 3 \times 3$

$90 = 2 \times 3 \times 3 \times 5$

Out of all factors 3 is the only common factor. Therefore the highest common factor is 3.

3) LCM of 24,56,168 is $168$

LCM of 12,18,60 is $180$

LCM of 35,49,567 is $10395$
