初等代数 示例

Since ${\displaystyle \frac{b}{7},-\frac{24}{35}}$ contains both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part, then find GCF for the variable part.

求数值部分的公因数：

${\displaystyle \frac{1}{7}}$ 的因式为 ${\displaystyle 1}$ 及其本身。

${\displaystyle -\frac{24}{35}}$ 的因式为 ${\displaystyle 1}$ 及其本身。

列出 ${\displaystyle \frac{1}{7},-\frac{24}{35}}$ 的所有因数以找出公因数。

${\displaystyle \frac{1}{7},-\frac{24}{35}}$ 的公因数为 ${\displaystyle 1}$。
