What are 2 numbers that have 3 factors?
Answer: As it turns out, the only positive integers with exactly three factors are the squares of primes. For instance, the factors of 9 are 1, 3, and 9, and the factors of 49 are 1, 7, and 49.
What is a number with multiple factors?
9 is a multiple of 3 is true because 3 x 3 = 9. 5 is a factor of 15 is true because: 5 x 3 = 15. 7 is a multiple of 21 is false because many are always greater than equals that number….What are the differences between a factor and a multiple?

What does a factor of 3 mean?
Last year there were 3000 observations, this year there are only 1000. This is described as showing a “fall by a factor of 3”. This phrase doesn’t ring true. If a factor of 3 is a 1/3, then a fall by a third would be down to 2000. So the phrase is meant to represent a fall to a third.

What is the meaning of factor in numbers?
The meaning of factor is a whole number that can divide a greater number evenly. Each prime number will have only two factors, i.e. 1 and number itself, whereas each composite number will have more than two factors, that include prime factors also.
How to find the total number of factors for a number?
Number of Factors. The formula for the total number of factors for a given number is given by; Total Number of Factors for N = (a+1) (b+1) (c+1) Sum of Factors. The formula for the sum of all factors is given by; Sum of factors of N = [(X a+1-1)/X-1] × [(Y b+1-1)/Y-1] × [(Z c+1-1)/Z-1] Product of Factors
Which is a factor of the number 12?
