21
The LCM is 21.
To find the Least Common Multiple (LCM) of 7, 3, and 21, we first need to identify the prime factors of each number. The prime factors of 7 are 7, of 3 are 3, and of 21 are 3 and 7. Then, we take the highest power of each prime factor that appears in any of the numbers. In this case, the LCM of 7, 3, and 21 is 21, as it includes the highest power of both 7 and 3.
It is typical to only find the lowest common multiple or LCM for a maximum of 3 numbers. The LCM of 3, 2, 7 is 42 and the LCM of 3, 2, 5 is 30.
Multiply them together.
21 is the LCM of 3 and 7
You need at least two numbers to find an LCM. If that's 2, 3 and 7, the LCM is 42.
The Least Common Multiple (LCM) of 7, 3, and 6 is 42.
The LCM is 105.
The LCM is 63.
The LCM is: 21LCM of 3 & 7 is 21.
To find the Least Common Multiple (LCM) of 3, 7, and 9, we first need to find the prime factors of each number. The prime factorization of 3 is 3, 7 is 7, and 9 is 3^2. To find the LCM, we take the highest power of each prime factor that appears in the factorization of any of the numbers. Thus, the LCM of 3, 7, and 9 is 3^2 * 7 = 63.
lcm(3, 7, 15) = 105. 3 = 3 7 = 7 15 = 3 x 5 lcm = 3 x 5 x 7 = 105
