How is 4 the HCF of 28 and 60?
To figure out the HCF of 28 and 60, split them up into their prime factors: 28 = 2x2x7 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Therefore 4 is the HCF of 28 and 60.
Prime numbers in the factors of 60?
The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The prime numbers are 2, 3, and 5.
Why is 60 not a prime number?
Because a prime number is a number that has exactly two factors: 1 and itself. 60 has 12 factors: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.
Is 3x5x4 a prime factorization of 60?
No, 3x5x4 is not a prime factorization of 60. A prime factorization of 60 would consist of only prime numbers. The prime factorization of 60 is 2x2x3x5.
What are the set of numbers that when multiplied will make a certain number?
They are that number's factors.If its the complete set of the smallest such numbers, they are the prime factors.What's the difference? 4 and 15 are factors of 60: 4 x 15 = 60.But the prime factors of 60 are 2 x 2 x 3 x 5. (Note that these are all prime numbers, which is where the term comes from.)By multiplying the prime factors in different combinations -- such as 2 x (2 x 3) x 5 -- we can come up with all the possible combinations which lead to the original number.Also note that the only prime factor of a prime number is itself. Some teachers will tell you that the factors of a prime number are itself and 1, which is also true: 1 (known as unity) is special in that every number, when divided by it, remains the same. But 1 itself is not considered a prime number.
What 4 numbers make 60?
As a product of its prime factors: 2*2*3*5 = 60
What is the HCF of 16 48 and 60?
The Highest Common Factor (HCF) of 16, 48, and 60 is 4. To find the HCF, you need to factorize each number into its prime factors. The prime factors of 16 are 2^4, the prime factors of 48 are 2^4 * 3, and the prime factors of 60 are 2^2 * 3 * 5. The HCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 = 4.
How is 4 the HCF of 28 and 60?
To figure out the HCF of 28 and 60, split them up into their prime factors: 28 = 2x2x7 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Therefore 4 is the HCF of 28 and 60.
What are the factors of 20 and 60?

What is the greatest common factor of 32 and 60?
The GCF of 32 and 60 is 4. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 32 are 1, 2, 4, 8, 16, and 32. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The common factors are 1, 2, 3, and 4. Therefore, the greatest common factor is 4. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 32 are 2, 2, 2, 2, and 2. The prime factors of 60 are 2, 2, 3, and 5. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
