The prime factorization of 48 is 24∗3 2 4 ∗ 3 .
What is the prime factorization 36?
We can write 36 as a product of prime factors: 36 = 2² × 3². The expression 2² × 3² is said to be the prime factorization of 36.
Which of the following is the prime factor form of 72?
So, the prime factors of 72 are written as 72 = 2 × 2 × 2 × 3 × 3.
What is the exponent of 3 in the prime factorization of 144?
As there are two 3’s the exponent of 3 is 3 square.
How to find the prime factorization exponential form of 72?
Taking the left-hand numbers and the right-most number of the last row (dividers) an multiplying then, we have. 72 = 2 x 2 x 2 x 3 x 3. 72 = 2 3 x 3 2 (prime factorization exponential form) Note that these dividers are the prime factors. They are also called the leaves of the factor tree.
What is the factorization of 72?
The number 72 is a composite number so, it is possible to factorize it. In other words, 72 can be divided by 1, by itself and at least by 2 and 3. A composite number is a positive integer that has at least one positive divisor other than one or the number itself.
Why is 72 not a prime number?
A prime number is an integer greater than one which is divided only by one and by itself. For example, the only divisors of 7 are 1 and 7, so 7 is a prime number, while the number 72 has divisors deived from 2 3 •3 2 like 2, 3, 4, 6, 8, 12, 24 and 72 itself, making 72 not a prime number.
What is 72 as a composite number?
In other words, 72 can be divided by 1, by itself and at least by 2 and 3. A composite number is a positive integer that has at least one positive divisor other than one or the number itself. In other words, a composite number is any integer greater than one that is not a prime number.
