Yes. Example: 1/30 and 1/42 2 x 3 x 5 = 30 2 x 3 x 7 = 42 2 x 3 x 5 x 7 = 210, the least common denominator.

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.

The least common denominator (LCD) is 1.There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.

The least common denominator of 9 and 15 (if they are denominators) is the least common multiple of those numbers. We denote this the LCD. One way to find that is write the prime factorization of the two numbers. 9 = 3^2 15 = 3 x 5 Take 3^2 x 5 = 9 x 5 or 45 is the LCM of 9 and 15. This is the product of the primes with the largest exponents. So the LCD or least common denominator is the LCM of 9 and 15 and this is 45.

The LCM of 3, 6, and 12 is 12.The least common denominator is the same as the least common multiple.The least common denominator is the smallest multiple divisible by 3, 6, and 12. Since 12 is divisible by 3, 6, and 12, and the smallest multiple of 12 is 12 x 1 = 12, that is the least common denominator or least common multiple.

Least common multiple is 429 39 = 3 x 13 33 = 3 x 11 Thus the LCM is 3 x 11 x 13 = 429

The common factor is 3. (105 = 35 x 3, 12 = 4 x 3).The least common denominator is 420.105 = 3 x 5 x 712 = 22 x 3Highest exponents method: 22 x 31 x 51 x 71 = 420

Yes. Example: 1/30 and 1/42 2 x 3 x 5 = 30 2 x 3 x 7 = 42 2 x 3 x 5 x 7 = 210, the least common denominator.
