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.
The lowest common factor of any set of positive integers is 1.
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.
Common factors of 30 and 3 are: 1 and 3.
The LCF of 4 & 7 is... 1 ! There are no other common factors.
Lowest common factors: 2 and 5 Greatest common factor: 10

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.
To find the greatest common factor and lowest common multiple of two numbers, you first need to split those numbers up into their prime factors. In this case: 8 = 2x2x2 12 = 2x2x3 The next step is to identify any common factors. In this case the common factors are two 2s. To find the greatest common factor, you multiply these together: 2x2 = 4. A quick way to find the lowest common multiple is to multiply the two original numbers together and divide by the greatest common factor. So 8x12/4 = 24. Thus 24 is the lowest common multiple.
