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
To find the Highest Common Factor (HCF) of 45, 75, and 125, we need to first find the prime factors of each number. The prime factors of 45 are 3 x 3 x 5, the prime factors of 75 are 3 x 5 x 5, and the prime factors of 125 are 5 x 5 x 5. To find the HCF, we look for the common prime factors among all three numbers, which are 5. Therefore, the HCF of 45, 75, and 125 is 5.
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.
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
The factors of 20 are: 1, 2, 4, 5, 10, 20The factors of 25 are: 1, 5, 25
215 = 5 * 43 (So we expect 4 factors) They are as follows: 1, 5, 43, 215
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.
The prime factors of 50 are: 2 and 5
Divide by 2 and 5. 1,2,5,10,25,50
Divide those 5 into your number. The whole number quotients will also be factors.
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.
