It is: 21
The LCM is 21.
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.
The LCM is 84.
The LCM is 105.
The LCM is 42
LCM of 5 7 21 is 105.
The LCM of 7 21 35 is 105
Its so easy. I can answer it in 1 second. The LCM is 105 (66) (51)
To find the Least Common Multiple (LCM) of 7, 14, and 21, we first need to factorize each number. The prime factors of 7 are 7, of 14 are 2 x 7, and of 21 are 3 x 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers. Therefore, LCM(7, 14, 21) = 2 x 3 x 7 = 42.
The LCM is 252.
The LCM is 42.
