The least common multiple of the numbers 8, 20 and 70 is 280.

The least common multiple of the numbers 20, 50 and 70 is 700.

The Least Common Multiple (LCM) for 12 20 70 80 is 1,680.

The least common factor of any set of numbers is 1.

LCD(70, 80) = 560

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.

That's two different things. The common factors of 350 and 420 are 1, 2, 5, 7, 10, 14, 35, 70, with 70 being the GCF. The least common denominator of 350 and 420 is 2100.

1/10 + 2/7 = 7/70 + 20/70 = 27/70

First find the common denominator, which is 70. Then convert both fractions to the common denominator. Then add the numerators. Last, convert to simplist terms. 7/10-2/7=49/70-20/70=29/70 29/70 is already in simplist terms, so the answer is: 29/70.

For something to have a common denominator, you would need two fractions to compare with each other. e.g, 1/2 and 7/2 have a common denominator.The number 70 can have a denominator 1, i.e. 70/1 = 70. It could also be written as 140/2=70. You would need another fraction to compare it to.
