Many people find factor trees to be the easiest.
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.
To find a prime factorization, divide a composite number and its factors by prime numbers until all the factors are prime. Many people find factor trees helpful in visualizing this process. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 is the prime factorization of 210.
You can find out the number of factors of any number from its prime factorization by adding one to each exponent and multiplying. The prime factorization of 156 is 2^2 x 3^1 x 13^1 3 x 2 x 2 = 12 156 has 12 factors.
