To find the Least Common Multiple (LCM) of 7, 21, and 35, we first need to find the prime factorization of each number. The prime factors of 7 are just 7, the prime factors of 21 are 3 and 7, and the prime factors of 35 are 5 and 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers: 7 (from 7), 3 (from 21), and 5 (from 35). Multiplying these together gives us the LCM: 7 x 3 x 5 = 105. Therefore, the LCM of 7, 21, and 35 is 105.
The LCM of 7 21 35 is 105
The LCM of 7, 21 and 35 is 105.
35 and 7, respectively.
The LCM of 5 and 7 is 35. LCM stands for Least Common Multiple, or Lowest Common Multiple.
Note that 21 x 2 = 42, so we really only need to look at 35 and 42. So 7 x 5 = 35, and 7 x 6 = 42. There is a common factor of 7. So we have 7 x 5 x 6 = 210 is the LCM.
