2 x 2 x 2 x 2 = 16
2 x 13 = 26
2 x 2 x 2 x 2 x 13 = 208, the LCM
The LCM of the given three numbers using prime factorization is 25200
You need at least two numbers to find an LCM no matter what you use.
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
speed you can just use your brain to find the LCM faster, sometimes.
The prime factorization of 4 is 2 x 2. It is not possible to find the LCM of a single number.
You need at least two numbers to find an LCM no matter what method you choose.
That appears to be the prime factorization of 14175. If you compare that to the prime factorization of another number, you will be able to find the LCM between the two.
That depends on the value of A.
It is: 60
