To find the Least Common Multiple (LCM) of 15, 21, and 35, we first need to find the prime factorization of each number. The prime factorization of 15 is 3 x 5, 21 is 3 x 7, and 35 is 5 x 7. Then, we identify the common and uncommon prime factors among the numbers. The LCM is calculated by multiplying all the prime factors together, including the highest power of any repeated factors. Therefore, the LCM of 15, 21, and 35 is 3 x 5 x 7 = 105.
