The factors of 17 are 1 and 17. The factors of 19 are 1 and 19. The only common factor is 1. Therefore, the least (lowest) common factor is 1 and the greatest (highest) common factor is 1.
The common denominator is usually the Lowest (or Least) Common Multiple of the numbers involved. Where two numbers have no common factors then the LCM is simply the product of those numbers. As 19 is a prime number and has no factors in common with 18 then the common denominator is 18 x 19 = 342.
You need at least two denominators to find something in common between them.
The Least Common Multiple of 17,18 and 19 is 5814.
It is not possible to give a sensible answer to this question. The least common denominator (LCD) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question: 5/6.
The LCD of 5, 17 and 19 is 1615.
38 is.
133
It is 76
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
19
lcd(8, 19) = 152.
It is: 1330
133
It is: 95
19 is prime, so multiply 19 by 112.
