The Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions. I assume the 7 and 21 are the denominators of two fractions you need to add or subtract.LCD(7, 21) = 21.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions.
They are 7 and 5
The LCM of 7 and 15 is 105.The prime factorization of 7 = 7The prime factorization of 15 = 3 * 5The least common multiple is the product of the pair divided by their GCF, which is 1.= 3 * 5 * 7= 105Their product.
