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 prime factorization 2x2x2x3x7 represents the number 168. This is because when you multiply 2x2x2x3x7, you get 168. Prime factorization is the process of breaking down a number into its prime factors, which are the building blocks of the number. In this case, the prime factors of 168 are 2, 2, 2, 3, and 7.
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.
yes its 3x5x5

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
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.
Notice whether the number is odd or even. If it's even, the first prime factor is 2.
it is a way of finding out all of the prime numbers that you have to multiply to equal the desired number.
