Five has no even factors and is therefore a Prime number. 5 is a prime number. Its only factors are one and itself.
25 = 5 x 5 Improved Answer:- Factors of 25 are: 1, 5 and 25
Factors for 20 are: 1, 2, 4, 5, 10, 20 Prime Factors: 2, 5 sum of prime factors = 2 + 5 = 7
Prime Factors of 15 are 3 and 5 Prime Factors of 25 are 5 and 5 Obviously 5 is the GCF, however, in general find the prime factors and multiply all the common factors. The GCF is 5.
The factors of 20 are: 1, 2, 4, 5, 10, 20The factors of 25 are: 1, 5, 25
To find the gcf, you need to find the factors for the two numbers (or more). Factors of: 55: 1,5,11,55 75: 1,3,5,15,25,75 Common factors: 1, 5 Greatest common factor: 5
215 = 5 * 43 (So we expect 4 factors) They are as follows: 1, 5, 43, 215
The prime factors of 50 are: 2 and 5
Find all the factors of each of the numbers. 25 - 1, 5, 25 35- 1, 5, 7, 35 The common factors are 1 and 5. The largest of these (5) is the GCF.
Divide by 2 and 5. 1,2,5,10,25,50
The prime factors of 100 are 2 x 2 x 5 x 5, and one more x 2 gives the prime factors of 200, 2 x 2 x 2 x 5 x 5. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. These are also the common factors of 100 and 200, but there is no obvious way to find the factors of 200 by using common factors. The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.
Divide those 5 into your number. The whole number quotients will also be factors.
The prime factors of 30 are: 2 + 3 + 5 = 10
