∙ 9y agoThe way to be sure you have one of these is to take any three distinct prime numbers and multiply them. Those three prime numbers are then the only factors the product can have. An example is the number 30, which has factors of 2, 3 and 5.
It is 2, 10, and 11
Numbers with exactly three factors are squares of prime numbers.
Average of three = 20 so total of three = 60; 60 - (28 + 15) = 60 - 43 = 17
All composite numbers have more than two factors. The smallest such number is 4, which is equal to 2 x 2. 4 has three factors: 1, 2, and 4.
144, 121 and 100
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
Yes. Square numbers have an odd number of factors. 49 has three factors.
Calculate their prime factors.
The numbers with only three factors are squares of prime numbers.
There is no common factors or GCF for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
Squares of prime numbers have three factors.
Squares of prime numbers are the only numbers with three factors, since there must be only one nontrivial divisor for a number to have three factors. That number must thus be prime.
A number has exactly three factors if and only if it is the square of a prime number.
