Find the common factor and greatest common factor (GCF) of two-four numbers using continuous division.
What is the greatest common factor (GCF) of two or more numbers?
How do you find the GCF of two or more numbers?
How do you compare the GCF of two or more numbers with the given numbers?
Relatively prime numbers - no common factors other than 1.
Visual Activity:
Use Continuous division to find the GCF of each set of numbers.
1. 5 = ________________________________
15 = ________________________________
GCF = ________________________________
2. 6 = ________________________________
16 = ________________________________
GCF = ________________________________
3. 14 = ________________________________
60 = _______________________________
GCF = _______________________________
4. 16 = _______________________________
32 = _______________________________
5. 20 = _______________________________
30 = _______________________________
GCF = _______________________________
The greatest common factor (GCF) of two or more numbers is the largest number that is a factor or divisor of each number.
To find the GCF of two or more numbers, you can first find the prime factors of each number by using any of the following methods: listing, factor tree, continuous division method.
The GCF of a set of numbers is either less than the numbers or equal to one of the numbers.
