You need at least two fractions to find something in common.
5 factors into 1 and 5 6 factors into 2 and 3 Therefore, the least common multiple is 1*2*3*5 = 30 This is what you would use for the LCD, convert the fifths and sixths into thirtieths.
5 = 5 12 = 2² x 3 15 = 3 x 5 2² x 3 x 5 = 60
the LCD of 2, 9 and 5 = 90
2/3 and 3/4Looks like 12 here, so use form of one to convert both fractions to LCD form.4*2/4*3 and 3*3/3*48/12 and 9/12==========

The LCD of 13, 14 and 15 is 2730 The LCD of 1/3, 1/4 and 1/5 is 60

The LCD for 1/5 and 4/15 is 15.
To find the least common denominator (LCD) of the fractions 14/15 and 11/12, first identify the denominators: 15 and 12. The prime factorization of 15 is 3 × 5, and for 12, it is 2^2 × 3. The LCD is found by taking the highest power of each prime factor: 2^2 (from 12), 3 (from both), and 5 (from 15). Thus, the LCD is 2^2 × 3 × 5 = 60.
Well, isn't that a happy little question! The least common denominator of 15 and 16 is 240. We can find this by multiplying the two numbers together, as 15 multiplied by 16 equals 240. Remember, there are no mistakes in math, just happy little accidents!
7/10 - 3/15 = 15/30 = 1/2Why?You need to find the LCD (least common denominator) which is 30. Look at the work below. You must keep in mind that whatever you do to the denominator, you must do to the numerator.7/ time 3 = 21/10 time 3 = 30- 3/ time 2 = 6/15 time 2 = -3021 - 6 = 15= 15/30 = 1/27/10 - 3/15 = ?Since 3/15 can be easily reduced to 1/5, we have:7/10 - 1/5 = ?Then, we find the LCD of 5 and 10, which is 10, by multiplying 2 to the numerator and denominator of 1/5:7/10 - 2/10 = 5/10 = 1/2.Another method includes using the basic fraction and finding the LCD:7/10 - 3/15 = ?The LCD (LCM) is 10/5 * 15/5 * 5 = 2 * 3 * 5 = 30. Thus, multiply 3 to the numerator and denominator in 7/10, and 2 to 3/15 in the same fashion.21/30 - 6/30 = 15/30 = 1/2.

The LCD of x, 5, 7, 15 is 105x.
You need at least two fractions to find something in common.
To add the fractions ( \frac{1}{3} ) and ( \frac{11}{5} ), we first need to find the least common denominator (LCD). The denominators are 3 and 5; their least common multiple is 15. Thus, the LCD is 15.
