As a product of its prime factors: 2*2*2*3*3 = 72
17 is a prime number. It is only evenly divisible by itself and one.The factors of 21 are: 1, 3, 7, and 21.The prime factors of 21 are: 3 and 7.
2 and 3
It is: 6
Factor trees create prime numbers. Prime numbers are positive. Since the prime factors of negative 72 are the same as positive 72, you might as well do positive 72. 72 36,2 18,2,2 9,2,2,2 3,3,2,2,2
To work this out, you first need to break the numbers down into their prime factors. This gives: 72 = 2x2x2x3x3 27 = 3x3x3 The next step is to identify any common prime factors. In this case both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Therefore the HCF of 72 and 27 is 9.
The prime factors for 72 are: 2, 3
The greatest common factor (GCF) of 27 and 72 is 9. The common factors of 27 and 72 are 1, 3, and 9. Methods: One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 27 are 1, 3, 9, and 27. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 27 are 3, 3, and 3. The prime factors of 72 are 2, 2, 2, 3, and 3. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
Apart from 1, all of the other factors of 72 are multiples of prime factors.
There are only 2 prime factors for 72. They are 2 and 3, since 72 = 2X2X2X3X3. Therefore, the 2 prime factors for 72 are 2 and 3.
The prime factors of 72 are 2 and 3.
There are two prime factors of 72: 2 and 3.
As a product of its prime factors: 2*2*2*3*3 = 72
Prime factor each number. Circle the factors that are in all three numbers. Multiply those factors. 27=3x3x3 54=2x3x3 72=2x2x2x3x3 3x3=9 is the GCF
The factors of 72 that are prime numbers are 2, 3, and 5. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder. In the case of 72, it can be broken down into the prime factors 2^3 * 3^2, where 2 and 3 are the prime factors.
1, 3, 9, 27 3 is prime. 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144 2 and 3 are prime.
the prime factors of 72 are 2 and 3 6,12, and 1 (also factors) sum up to 19
