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.

The first step of finding the GCF is to split the numbers into their prime factors. For instance, if I wanted to find the GCF of 30 and 105, I would split these up into: 30 = 2x3x5 105 = 3x5x7 The next step would be to identify any common prime factors. In this case both numbers have 3 and 5 as prime factors, so these would be the ones we use. To find the GCF, you simply multiply these two numbers together: 3x5 = 15 So 15 would be the GCF in that case.

To find the HCF of two numbers you first need to break them down into their prime factors. In this case we get: 36 = 2x2x3x3 48 = 2x2x2x2x3 The next step is to identify any common prime factors. In this case, both numbers have two 2s and a 3 as prime factors. Multiply these together and you get 12. Therefore, the HCF of 36 and 48 is 12.

Step 1: 2 x 2 = 4 Step 2: 4 x 2 = 8 Step 3: 8 x 3 = 24 Step 4: 24 x 7 = 168 (also how many hours there are in a week)! The prime factorisation is 168.

The prime factorization of 93 is 3 x 31. Draw it however you wish.

It is: 2*2*5*5 = 100

It is itself because 31 is a prime number

Notice whether the number is odd or even. If it's even, the first prime factor is 2.
