The lowest common factor of any set of integers is 1.
You would find the factors of each and cancel any they have in common. But 15 and sixteen do not have common factors, therefore 15 over 16 is already in lowest terms.
They can help you to find the Lowest Common Multiple and Highest Common Factor of numbers which is useful when dealing with fractions.
The lowest common multiple is 5832 which would be used for the LCD. 729 is 36 and 8 is 23. Since they have no common factors, you find the LCD by multiplying the two numbers.
To find the greatest common factor (GCF) of two factors, first list the factors of each number. Then, identify the common factors between them. The GCF is the largest of these common factors. Alternatively, you can use the prime factorization method, where you break down each number into its prime factors and multiply the lowest powers of all common prime factors.
The lowest common factor of 140, 150, and 180 is 10. To find the lowest common factor, you can first find the prime factors of each number (140 = 2^2 * 5 * 7, 150 = 2 * 3 * 5^2, 180 = 2^2 * 3^2 * 5). Then, identify the common prime factors and multiply them together. The highest common factor of these numbers is 10, as it is the largest number that can evenly divide all three numbers without leaving a remainder.
The lowest common factor of any set of positive integers is 1.
Common factors of 30 and 3 are: 1 and 3.
Lowest common factors: 2 and 5 Greatest common factor: 10
The LCF of 4 & 7 is... 1 ! There are no other common factors.

Look for common factors. Then divide both top and bottom by such common factors. Continue, until you can find no more common factors.
Yes that is the most effective approach in reducing fractions and finding their lowest common denominator.
