# Re: [PHP] Fractions

```Well how would you do it on paper?

\$numerator = 8;
\$denominator = 12;```
```
\$factor = 1;

//Start at the greater of the 2, and loop down til you find a common factor
for (\$i=max(\$numerator,\$denominator);\$i>1;\$i--) {
//Check if each number divided by \$i has no remainder
if ((\$numerator % \$i) == 0 && (\$denominator % \$i) == 0) {
//Factor Found
\$factor = \$i;
break;
}
}

//Now a factor is found, divide by it
\$numerator = \$numerator / \$factor;
\$denominator = \$denominator / \$factor;

echo \$numerator . '/' . \$denominator;

The method might look like the above
