How do you write 42 as a product of its ' factors?

Lana Schwartz

Expert

Step 1
The lowest ' number is 2. So we begin by dividing 42 by 2.
$⇒42÷2=21$
Now 21 cannot be divided by 2 so we now divide by the next highest ' number which is 3.
$⇒21÷3=7$
Step 2
Now 7 is a ' number
$⇒7÷7=1$ when we reach 1 we stop there.
Prime factors of 42 are 2, 3 and 7 and as a product of ' factors, means expressing them in multiplication form.
$⇒42=2×3×7←\phantom{\rule{1ex}{0ex}}\text{product of ' factors}$
