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.
The LCM is: 84
the answer is 21 due to the fact that 7*3=21 and 21*1=21
2 x 3 x 3 = 18 3 x 7 = 21 2 x 3 x 3 x 7 = 126, the LCM
The LCM of 7 and 21 is 21. Since 7 is a factor of 21, the LCM is automatically 21.21 is.
lcm(49, 63, 21) = 441 49 = 7^2 63 = 3^2 x 7 21 = 3 x 7 lcm = 3^2 x 7^2 = 441
3: 3 28: 7, 2, 2 21: 7, 3 LCM = 3x7x4 = 84
It is: 42
2 x 7 = 14 3 x 7 = 21 2 x 3 x 7 = 42, the LCM
The LCM is 42
The LCM is 105.
The LCM is 84.

lcm(21, 56) = 168. 21 = 3 x 7 56 = 2^3 x 7 lcm = 2^3 x 3 x 7 = 168
21 = 3 * 7 60 = 2 * 2 * 3 * 5 LCM is 2 * 2 * 3 * 5 * 7 = 60 * 7 = 420.
LCM of 5 7 21 is 105.
The LCM of 7 21 35 is 105
