It is in exponents: 2^4 times 3^2 = 144
5 x 11
5 x 7 = 35
Each number is either itself a prime number, or it can be separated into smaller prime numbers. A prime number is a number that has no smaller factors. Factorization into prime factors is unique, except for the order of the factors.
144 is a composite number because it has more than two factors
You can determine the number you factored by re multiplying all the numbers. 2 • 3 = 6 • 5 = 30 • 7 = 210 • 11 = 2310. So the prime factorization of 2310 is 2 • 3 • 5 • 7 • 11.
Yes: Prime Ministers can be re-elected in Australia, and they frequently are. There is no limit to the number of consecutive times a Prime Minister can be re-elected.
The order of prime factors is not relevant in factorisation.
A prime number is a positive whole number (a positive integer) that has exactly two unique positive divisors, 1 and the number itself.
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
Itself and one because 7 is a prime number
To determine the prime factors of a number:Try to divide the number by the lowest prime number, which is 2. If it divides evenly mark that number down as one of the prime factors, and continue with the result, trying to divide that prime factor into it. Continue dividing that prime factor into the results until it no longer divides evenly. If it does not divide evenly, move to the next lowest prime number and repeat the process until you have a result that is a prime number. Now you have all the prime factors.Example: Find the prime factors of 128.The prime factors are in bold.128 ÷ 2 = 6464 ÷ 2 = 3232 ÷ 2 = 1616 ÷ 2 = 88 ÷ 2 = 44 ÷ 2 = 2 which is a prime factor and thus the final prime factor.Therefore, the prime factors of 128 are 2, 2, 2, 2, 2, 2, and 2; the prime factorization is 2 x 2 x 2 x 2 x 2 x 2 x 2.Example: Find the prime factors of 108.108 ÷ 2 = 5454 ÷ 2 = 2727 is not divisible by 2, so try 3.27 ÷ 3 = 99 ÷ 3 = 3 which is a prime factor and thus the final prime factor.Therefore the prime factors of 108 are 2, 2, 3, 3, and 3; the prime factorization is 2 x 2 x 3 x 3 x 3.Example: Find the prime factors of 1463.1463 is not divisible by 2 or 3 or 5, but it is divisible by 7.1463 ÷ 7 = 209209 is not divisible 7, so try the next prime number, which is 11.209 ÷ 11 = 19 which is a prime factor and thus the final prime factor.Therefore, the prime factors of 1463 are 7, 11, and 19; the prime factorization is 7 x 11 x 19.Another way to determine the prime factors is to use a factor tree. To make a factor tree, find two numbers whose product is the given number. Then, if those numbers are not prime, do the same for them. Continue until all numbers are prime.Example: Find the prime factors of 54 using a factor tree.546 x 92x3 x 3x3Therefore, the prime factors of 54 are 2, 3, 3, and 3; the prime factorization is 2 x 3 x 3 x 3.For other examples of factor trees, see the related question on factoring terminology.you find it by using exponents and by dividing the two numbersyou do a mutiple of that to get the number you re factoring by then make prime factor tree
