Prime factors can be divided only by 1 and by themselves.
13 can divide 169.
The prime factors of 1890 are: 2,3,5,7
Its prime factors are 29 and 41
Prime factors of numbers are small numbers that the bigger (original) number can divide by. The prime factors have to be prime. This means they only have two factors, itself and one.
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. 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.
Divide a number and its factors by prime numbers until all the factors are prime. 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. 2 x 3 x 5 x 7 = 210
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 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 = 210That's the prime factorization of 210.
Only composite numbers have factors. 601 does not divide evenly by anything, therefore it is a prime number. Since it is a prime number its only factors are one and itself.
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.
2, 3 and 5
The prime factors of 34 are 2 and 17.To find the prime factors, it is useful to divide the number by any obvious factors. 34 is even so can divide by 2. Doing this gives us 17. That's a prime number, so cannot be divided any further. Thus, the prime factors of 34 are 2 and 17.
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 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 = 210That's the prime factorization of 210.
