It is: 2*2*5*5 = 100
To find the Least Common Multiple (LCM) of 6, 7, and 18, we first need to find the prime factorization of each number. The prime factorization of 6 is 2 x 3, the prime factorization of 7 is 7, and the prime factorization of 18 is 2 x 3^2. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2 x 3^2 x 7 = 126. Therefore, the LCM of 6, 7, and 18 is 126.
Notice whether the number is odd or even. If it's even, the first prime factor is 2.
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.
The prime factorization of a number is all the prime numbers which, when multiplied by each other, equal the number. The prime factorization of 93 is 3 x 31, because 3 and 31 are both prime numbers which, when multiplied by each other equal 93.
yes its 3x5x5

290 145,2 29,5,2 2 x 5 x 29 = 290
It is: 2*2*5*5 = 100
It is itself because 31 is a prime number
You can find the prime factorization of 130: 130 = 2*5*13 Therefore the answer is 1. Or you can skip a step. Just divide 130 by 2. You get 65, which is an odd number. Therefore there is only 1 factor of 2 in the factorization of 130.
