Is 59 prime or a composite number?
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 59 does not have any factors besides 1 and itself (not more than two factors), so it is a prime number.
Which number less than 1000 has the most different prime factors?
210 has 4, which is the maximum possible. There are other numbers with 4 different prime factors.
What is the least common denominator of 143 and 208?
To find the least common denominator of 143 and 208, we need to first find the prime factors of each number. The prime factors of 143 are 11 and 13, while the prime factors of 208 are 2, 2, 2, 2, 13. The least common denominator is the product of all the prime factors with the highest power present in either number, which is 2^4 * 11 * 13 = 1144. Therefore, the least common denominator of 143 and 208 is 1144.
What is the name for a whole number that has exactly 2 factors?
Prime. The only factors of a prime number are 1 and the number.
What is all of the factors of 23?
As 23 is a prime number, it has only two factors, the number one and itself. The factors of 23 are: 1 23 The prime factors are: 23 is a prime number.
What is the least whole number the has two different prime factors?
6
Must a composite number have at least two different prime factors?
No, 4 has one prime factor.
What eight digit number does not have at least 3 different prime factors?
16,777,216 is one.
What is the least whole number that has 2 different prime factors?
6
What is the least whole number that has two different prime factors?
Just multiply the two smallest prime numbers. That's your number.
Is a composite number times a composite number always composite?
Yes. To be composite, the first number has at least 2 prime factors, the second number also has at least prime factors; the product of the two will have at least 4 prime factors, so it must be a composite number.
Why does 2x3x4x5 give you the least number of factors?
The expression 2x3x4x5 can be simplified to 120. The number 120 has the least number of factors because it is a product of consecutive prime numbers (2, 3, and 5). When a number is a product of distinct prime numbers, it will have fewer factors compared to numbers with repeated prime factors. In this case, 120 only has 16 factors, making it the least among numbers with the same number of prime factors.
What is the least number that has three different prime factors?
If by "least number" you mean "smallest positive integer", then the answer is the product of the three smallest primes: 2x3x5 = 30
How is a prime number different from the factors?
A prime number has only two factors, one and the number itself. A composite number has more than two factors. Factors can be either prime or composite.
How is prime factorization different from finding factors of a number?
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.
What two digit number that has three different prime factors?
The only two-digit number that has three different prime factors is 2 x 3 x 5, which equals 30. This number has the prime factors 2, 3, and 5, all of which are distinct prime numbers. Any other two-digit number with three prime factors would have at least one repeated prime factor, making it not have three different prime factors.
What is the least number that is divisible by four different prime numbers?
the least number is 210 which is divisible by four different prime numbers.
