738 | 2 |

369 | 3 |

123 | 3 |

41 | 41 |

1 |

## 2. Write all numbers as the product of its prime factors

Prime factors of 738 | = | 2 . 3^{2} . 41 |

## 3. Choose the common prime factors with the lowest exponent

Common prime factors: 2 , 3 , 41

Common prime factors with the lowest exponent: 2^{1}, 3^{2}, 41^{1}

## 4. Calculate the Greatest Common Factor or GCF

Remember, to find the GCF of several numbers you must multiply the common prime factors with the lowest exponent.

**GCF** = 2^{1}. 3^{2}. 41^{1} = 738
