No, 60 and 75 are not relatively prime because their greatest common factor is 15 and not 1. In order for them to be relatively prime, 1 must be their greatest common factor.
An employer would consider the forecasts of workload and their budget> When considering whether to hire another worker they must consider the total cost of the employee such as benefits and insurance.
The greatest common factor (GCF) of two (or more) numbers is the greatest factor that divides two numbers. To find the GCF you must work out and list the prime factors of each of the numbers. You will see that the numbers have prime factors in common. Multiply those factors the numbers have in common together and this gives you the GCF for the numbers. eg Number A = 18, Prime factors = 2*3*3 Number B = 24, Prime factors = 2*2*2*3 The Prime factors that A and B have in common are 2 and 3 Multiply them together = 6 6= the GCF of 18 and 24
Only composite numbershave prime factorizations. Prime factorizations must consist of only prime numbers.
The greatest common factor of several numbers cannot be larger than the greatest common factor of any pair of the numbers. If you realize that the greatest common factor of 3 and 5 is 1, the greatest common factor of all the numbers must be 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 3 are 1 and 3. The factors of 5 are 1 and 5. The factors of 8 are 1, 2, 4, and 8. The factors of 10 are 1, 2, 5, and 10. The only common factor is 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 3 is 3. The prime factor of 5 is 5. The prime factors of 8 are 2, 2, and 2. The prime factors of 10 are 2 and 5. There are no prime factors in common, so the greatest common factor is 1.
What is the greatest prime you must consider to test whether 2834 is prime?
59
53
It is 157 because the prime factors of 6437 are 41 and 157
It is 149 because as a product of its prime factors: 7*149 = 1043
you would need to look at all numbers up to square root of n, which in this case is 75.
You don't have to test anything. Any number greater than 5 that ends in 5 is composite.
You only need to test numbers up to the last prime number equal to or less than the square root of a number when testing whether it is prime. The square root of 854 is between 29 and 30, so you would test up to the prime number 29.
43 is the greatest prime that needs to be used in determining if 2089 is prime.
You have to take the square root of the number (= 59,99) ==> You have to test all prime numbers smaller than 59,99. You will have to test these numbers: 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59
The answer is 1. The smallest prime is 2 and the greatest prime (of however many digits) must be odd. The remainder of ANY odd number when divided by 2 must be 1.
2 - it is an even number, so it has 2 as a factor and is not prime. (it is 2 x 5 x 89)For numbers just below 890, you can use its square root, 29.83 - the highest "lower factor of a pair" it could have is 29. If you test the lower primes (3, 5, 7, 9, 11, 13, 17, 19, 23, 29) and none is a factor, it would be prime.
