What are the prime factors and prime factors of 72?
Prime factors are the prime numbers that can be multiplied by a whole number to reach the objective. For 72, the prime factors are 2 and 3. Other factors include 1, 4, 6, 8, 9, 12, 18, 24, 36 and 72. The prime factorization is 2 x 2 x 2 x 3 x 3 = 72
What is the co-prime number for 72?
"The" co-prime number is wrong; for any number, there are infinitely other numbers that are co-prime with it, not just one. Get the prime factors for 72. Then, any number made up of factors that DON'T include those prime factors is co-prime with 72. For example, 49 (which is 7 x 7), or 35 (5 x 7) are coprime with 72, since neither 5 nor 7 are among the prime factors of 72.
How many prime factors does 72 have?
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.
What is the HCF of 72 and 27?
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.
Express 72 as a product of its prime factors?
To express 72 as a product of its prime factors, we first identify the prime numbers that can divide evenly into 72. We start by dividing 72 by the smallest prime number, 2, which gives us 36. Then, we divide 36 by 2 again to get 18. Next, we divide 18 by 2 to get 9. Finally, we divide 9 by 3 to get 3. Therefore, the prime factors of 72 are 2 x 2 x 2 x 3 x 3.
