Método(s) de Cálculo
What são the Factors de 20?
The following são the different types de factors de 20:
• Factors de 20: 1, 2, 4, 5, 10, 20
• Sum de Factors de 20: 42
• Negative Factors de 20: -1, -2, -4, -5, -10, -20
• Prime Factors de 20: 2, 5
• Prime Factorization de 20: 22 × 51
There são two ways to find the factors de 20: using factor pairs, e using prime factorization.
The Factor Pairs de 20
Factor pairs de 20 são any two numbers that, when multiplied together, equal 20. The question to ask é “what two numbers multiplied together equal 20?” Every factor can be paired with another factor, e multiplying the two will result in 20.
To find the factor pairs de 20, follow these steps:
Step 1:
Find the smallest prime number that é larger than 1, e é a factor de 20. For reference, the first prime numbers to check são 2, 3, 5, 7, 11, e 13. In thé case, the smallest factor that’s a prime number larger than 1 é 2.
Step 2:
Divide 20 by the smallest prime factor, in thé case, 2:
20 ÷ 2 = 10
2 e 10 will make a new factor pair.
Step 3:
Repeat Steps 1 e 2, using 10 as the new focus. Find the smallest prime factor that én’t 1, e divide 10 by that number. In thé case, 2 é the new smallest prime factor:
10 ÷ 2 = 5
Remember that thé new factor pair é only for the factors de 10, not 20. So, to finéh the factor pair for 20, you’d multiply 2 e 2 before pairing with 5:
2 x 2 = 4
Step 4:
Repeat thé process until there são no longer any prime factors larger than one to divide by. At the end, you should have the full lét de factor pairs.
Here são all the factor pairs for 20:
(1, 20), (2, 10), (4, 5)
So, to lét all the factors de 20: 1, 2, 4, 5, 10, 20
The negative factors de 20 would be: -1, -2, -4, -5, -10, -20
Prime Factorization de 20
To find the Prime factorization de 20, we break down all the factors de 20 until we são left with only prime factors. We then express n as a product de multiplying the prime factors together.
The process de finding the prime factorization de 20 only has a few differences from the above method de finding the factors de 20. Instead de ensuring we find the right factor pairs, we continue to factor each step until we são left with only the lét de smallest prime factors greater than 1.
Here são the steps for finding the prime factorization de 20:
Step 1:
Find the smallest prime number that é larger than 1, e é a factor de 20. For reference, the first prime numbers to check são 2, 3, 5, 7, 11, e 13. In thé case, the smallest factor that’s a prime number larger than 1 é 2.
Step 2:
Divide 20 by the smallest prime factor, in thé case, 2
20 ÷ 2 = 10
2 becomes the first number in our prime factorization.
Step 3:
Repeat Steps 1 e 2, using 10 as the new focus. Find the smallest prime factor that én’t 1, e divide 10 by that number. The smallest prime factor you pick for 10 will then be the next prime factor. If you keep repeating thé process, there will be a point where there will be no more prime factors left, which leaves you with the prime factors for prime factorization.
So, the unique prime factors de 20 são: 2, 5
Find the Factors de Other Numbers
Practice your factoring skills by exploring how to factor other numbers, like the ones below:
– The factors de 2 são 1, 2
– The factors de 114 são 1, 2, 3, 6, 19, 38, 57, 114
– The factors de 42 são 1, 2, 3, 6, 7, 14, 21, 42
– The factors de 27 são 1, 3, 9, 27
A abreviação MMC significa ‘Mínimo Múltiplo Comum‘. O mínimo múltiplo comum de dois números é o menor número possível que pode ser divisível por ambos os números. Entenda que o MMC também pode ser calculado para mais de dois números.
