The lowest common factor of any set of numbers is 1.
The greatest common factor of several numbers cannot be larger than the greatest common factor of any pair of the numbers. If you realize that the greatest common factor of 3 and 5 is 1, the greatest common factor of all the numbers must be 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 3 are 1 and 3. The factors of 5 are 1 and 5. The factors of 8 are 1, 2, 4, and 8. The factors of 10 are 1, 2, 5, and 10. The only common factor is 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 3 is 3. The prime factor of 5 is 5. The prime factors of 8 are 2, 2, and 2. The prime factors of 10 are 2 and 5. There are no prime factors in common, so the greatest common factor is 1.
