Here is a handy little GCF Calculator that you can use to find the GCF of two numbers 4, 5 i.e. 1 the largest number that divides both the numbers exactly.

Greatest Common Factor of 4 and 5 is 1

GCF(4, 5) = 1

**Ex:** number 1 - 1500 and number 2 - 20.

Given Inputs are 4, 5

To find the GCF using the Prime Factorization Method you just need to list out the prime factors of both the numbers.

**Prime Factorization of 4 as under**

2 | 4 |

2 | 2 |

1 |

Prime factors of 4 are 2. Prime factorization of **4** in exponential form is:

4 = 2^{2}

**Prime Factorization of 5 is as such**

5 | 5 |

1 |

Prime factors of 5 are 5.Prime factorization of **5** in exponential form is:

5 = 5^{1}

Occurrences of Common Prime Factors from both the numbers 4 and 5 is 1

Therefore, GCF of two numbers 4 and 5 is 1

Given input data is 4, 5

Make a list of factors for the corresponding input numbers

**Factors of 4**

List of positive integer factors of 4 that divides 4 without a remainder.

1,2,4

**Factors of 5**

List of positive integer factors of 5 that divides 5 without a remainder.

1,5

Figure out the highest common factor from factors of both the numbers and that is the GCF. In this case, it is 1

Therefore, GCF of two numbers 4 ad 5 is 1
