Notice whether the number is odd or even. If it's even, the first prime factor is 2.
The first step in finding the Least Common Multiple (LCM) of two or more numbers is to determine the prime factorization of each number. This involves breaking down each number into its prime factors. Once you have the prime factorization of each number, you can identify the common factors and the highest power of each prime factor that appears in any of the numbers. Finally, multiply these common factors together to find the LCM.
It is: 2*2*5*5 = 100
The prime factorization of 93 is 3 x 31. Draw it however you wish.
first step in what!
The prime factorization of a number uses only primes. Ex: The prime factorization of 12 is not 6 x 2, and not 4 x 3, because 6 and 4 are not prime numbers. The prime factorization is 2 x 2 x 3. Their product is 12 and all factors are prime numbers. To get a prime factorization you are usually taught to factor through division by small prime numbers, sometimes you must use the same number more than once as in the example of 12 above 2 was used twice. Ex: find the prime factorization of 18. The smallest prime is 2... divide by 2 18 / 2 = 9 .... for the next step divide 9 by a prime 9 / 3 = 3 ... this is a prme ... it is also a factor so the prime factorization is 18 = 2x3x3 Ex. find the prime factorization of 35. 35 cannot be divided by 2, or 3, so use 5 first 35 / 5 = 7 .... since 7 is a prime we are finished. The prime factorization of 35 is 35 = 5 x 7 Some teachers teach this using a "factor tree" .. I can't type one of those on a computer.
If the first step is writing down the numbers, the second step is finding their prime factorizations.

Prime factorization of 46 is 2 X 23. We can do this easily by taking it one step at a time: First, 46 is an even number so we can divide it by 2. Since 2 is prime, it must be a prime factor! Now we have 23, which is a prime number. Double check: 2 * 23 = 46, and we're done!

it is a way of finding out all of the prime numbers that you have to multiply to equal the desired number.
