290 145,2 29,5,2 2 x 5 x 29 = 290
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.
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.
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.
Prime factorization is breaking down a number into all of the prime numbers that make it up.For example, in 128, since it is even, the easiest first step would be diving by two, a prime number.64 * 2 = 128. Now divide 64, another even number, by two.32 * 2 * 2 = 128. Divide 32 by two.16 * 2 * 2 * 2 = 128. Divide by two again.8 * 2 * 2 * 2 * 2 = 128. Divide by two again.4 * 2 * 2 * 2 * 2 * 2 = 128. Divide by two a final time.2 * 2 * 2 * 2 * 2 * 2 * 2 = 128. This is your prime factorization.But you write it condensed, so 27 would be the prime factorization for 128.
yes its 3x5x5
75 25,3 5,5,3
2 ^ 1 2
It is: 2*2*5*5 = 100
1040 520,2 260,2,2 130,2,2,2 65,2,2,2,2 13,5,2,2,2,2

The prime factorization of 93 is 3 x 31. Draw it however you wish.
290 145,2 29,5,2 2 x 5 x 29 = 290
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.
it is a way of finding out all of the prime numbers that you have to multiply to equal the desired number.
