The common factor of both 15 and 27 is 3.
There's no such thing as "common factors" of a single number."Common" means "same for both".A "common" factor is a number that's a factor of at least two different numbers.The factors of 15 are: 1, 3, 5, and 15.Find another number that also has any of these as a factor, and you'll have a 'common' factor.
Short answer: 3/4 How to solve: To simplify fractions, look for a common factor in both the numerator (top number) and denominator (bottom number), then divide both by that factor. In this case, 15 is the greatest common factor. Divide both 45 and 60 by 15, and you get 3/4.
The greatest common multiple of 7 and 15, like any two numbers, is infinite.The lowest common multiple, the smallest number into which both 7 and 15 divide, is 105The greatest common factor, the largest number which divides both 7 and 15, is 1.
Because it is the largest number that divides into both 6 and 15 evenly with no remainder.
You need a second number to have a highest common factor or it is infinite
The LCF, or Lowest Common Factor, of 3 and 5 is 15. This is because 15 is the smallest number that both 3 and 5 can divide into evenly. In other words, 15 is the smallest multiple that is common to both 3 and 5.
The least common factor is: 1
You find the highest common factor of both numbers and divide each number by it.
Take the gcf (greatest common factor) of 15 and 60 and divide both the numerator and the denominator by that number.
15 and 30 is just one pair of number that has a greatest common factor of 15
You need at least two numbers to find something in common, but I'll save you the trouble. The least common factor of 15 and anything is 1.
