To find the LCM Factorise. 4 = 2 x 2 10 - 2 x 5 '2' is a common factor , so we are left with another '2' & a '5' Hence # 2 x 2 x 5 = 4 x 5 = 20 the LCM
To find the least common multiple (LCM) of 2, 4, and 10, we need to first find the prime factorization of each number. The prime factorization of 2 is 2, 4 is 2^2, and 10 is 2 * 5. To calculate the LCM, we take the highest power of each prime factor that appears in the factorizations of the numbers, which gives us 2^2 * 5 = 20. Therefore, the LCM of 2, 4, and 10 is 20.
Since 4 is a multiple of 2, it is automatically the LCM.
LCM stands for lowest common multiple. So, it has to be the lowest integer multiple of both 2 and 4. So the LCM of 2 and 4 is 4 not 2.
The LCM of 2 and 4 is 4.
