The greatest common denominator of any set of denominators is infinite.
Denominators can only be found in fractions. 105 and 63, therefore, cannot have common denominators. * * * * * 21 and any multiple of 21.
The least common multiple for 35 and 14 is 70
The least common multiple of the numbers 14, 35 and 21 is 210.
The LCM of 4, 10, and 35 is: 140
LCM = 56

The least common multiple of 14 and 35 is 70
The factors of 14 are 1, 2, 7, and 14. The factors of 35 are 1, 5, 7, and 35. The common factors of 14 and 35 are 1 and 7. Therefore, the least common factor (the smallest common factor) is 1. The greatest common factor of 35 and 14 is 7.
Denominators can only be found in fractions. 105 and 63, therefore, cannot have common denominators. * * * * * 21 and any multiple of 21.
No, they are integers. If they were denominators, their LCD would be 42.
Two fractions having different denominators cannot be added or subtracted directly. They need to be converted to equivalent fractions having the same denominator to enable the addition or subtraction to take place. It is possible to use the product of the denominators of the original fractions as the common denominator but it simplifies the mathematics if the lowest common multiple of the two denominators is used. EXAMPLE : Add 2/5 and 3/7. The lowest common denominator (also the LCM) of 5 and 7 is 35. 2/5 is equivalent to 2 x 7/5 x 7 = 14/35 : 3/7 is equivalent to 3 x 5/7 x 5 = 15/35 2/5 + 3/7 = 14/35 + 15/35 = 29/35
The Least Common Multiple (LCM) for 7 14 10 is 70.
Common multiples of 14 and 35 include 70, 140 and 210
The only common factor of 14 and 35 is 7 and 1 because only these numbers go into both 14 and 35.
