How many factors does the product of two prime numbers have?
4
Is 3 a prime or composite number why?
Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.
What is the GCF of 52 and 4?
To find the GCF of two numbers you first need to split them both into their prime factors. For 52 and 4 these are: 52 = 2x2x13 4 = 2x2 The next step is to identify any common factors. In this case, both numbers have two 2s as factors. To find the GCF you take these common prime factors and multiply them: 2x2=4. Thus the GCF of 52 and 4 is 4.
Find two composite numbers with a GCD of 1?
Any two numbers who are relatively prime will workSo look at 9 and 4. Neither is prime and their GCD is 1.You must need two numbers with NO other factors in common.
What is the HCF of 52 and 96?
To find the HCF of two numbers you first need to write them as the product of their prime factors: 52 = 2x2x13 96 = 2x2x2x2x2x3 The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiply these and you get: 2x2 = 4 Thus the HCF of 52 and 96 is 4.
What prime numbers have 4 factors?
None because prime numbers have only two factors
What are numbers that have 2 4 8 factors?
Numbers that have 2 factors are prime numbers; Numbers that have 4 factors are either: * the cube of a prime; or * the product of two different primes; Numbers that have 8 factors are either: * a prime to the power 7; * the product of a prime cubed and different prime; * the product of three different primes.
How many factors does the product of two prime numbers have?
4
Is 3 a prime or composite number why?
Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.
Why is it when you multiply two prime numbers you get a number with three or four factors?
If the two prime numbers are different: You get the two prime numbers, plus 1, plus the product. For example, if you multiply 2 x 3 = 6, the factors of 6 are 2, 3, 1, and 6. If the two prime numbers are the same: You get the prime number, 1, and the product. For example 2 x 2 = 4. The factors of 4 are 2, 1, 4.
Which of the numbers in questions 1-3 are prime numbers?
4
What is the two prime numbers for 135?
135 has 4 prime factors. They are 3 , 3 , 3 , 5.
What are two numbers that have no common factors greater than 1?
Such numbers, like 4 and 9, are called relatively prime or co-prime.
What is a whole number greater than 1 that is exactly two factors?
Any composite number. Examples: 4 and 9 . . . (three factors) 6, 8, and 10 . . . (four factors) 12 . . . (six factors) 60 . . . (twelve factors)
Is twenty prime or composite?
Twenty is composite. It has the factors 1, 2, 4 ,5, 10, and 20. Prime numbers have exactly two factors. Composite numbers have three or more.
Are 4 and 7 relatively prime?
Two numbers are relatively prime if and only if they share no common proper factors (other than 1, which is a factor of all numbers). The factors of 4 are 4 and 2, while 7 has no factors other than 1 and itself. Since 4 and 7 have none of the same proper factors, they are relatively prime.
What is relativly prime?
Relatively prime is when two numbers have no common factors other than 1. 9 and 4 are two such numbers: 9: 3 x 3 4: 2 x 2
