because 4 = 2 x 2 and 6 = 2 x 3 and you've already used 2 & 3.

What strategy do you use to find factors?
Assuming you want all factors of a number: 1) Split a number into prime factors. 2) Combine the prime factors in all possible ways. To get the prime factors, you can systematically try out dividing the number by prime numbers, up to the number's square root (once the square of the prime number you try out is greater than the original number, you need not continue). For example, to find out prime factors of numbers up to 120, you only need to try dividing by 2, 3, 5, 7.
How do you use a factors trees to find the prime factorization of 120?
120 60,2 30,2,2 15,2,2,2 5,3,2,2,2
How do you find the prime factors of 125?
Use a factor tree. 125 25,5 5,5,5
How do you use prime factorization to see if they are relatively prime?
If your numbers have no prime factors in common, they are relatively prime.
What are the numbers 77 is relativle prime to?
That's an infinite list. 76 and 78 are on it.
How do you use a factors trees to find the prime factorization of 2916?
i dont know thats why im asking you
How do you get the prime factors of 36?
Find 2 factors of 36 first -9 and 4- Now break these factors into smaller factors. That's your prime factorization. 9=3x3 4=2x2 3x3x2x2
How do you find out the common factors?
you use prime factorization
Can you use the factors of 36 to find the factors of 360?
Yes. Since 36 x 10 = 360, combine the prime factors of 36 with the prime factors of 10.
In gcf do you use factors or prime factors?
Either one will work. If you're listing factors, use factors. If you're using prime factorization, use prime factors.
How do you use the prime factorizations to find the LCM of a and b?
a and b have no common prime factors. Their LCM is their product.
How do you use Arrays to find factors of numbers?
You might use the array to store the results, since a number may be made up of several prime factors. As soon as you find a prime factor, save the result to the array, and continue looking for additional factors. If you want all factors, not just prime factors, the principle is the same; you can store the results of your calculations to an array.
How do you find the prime factors of 42?
Use a factor tree. 42 21,2 7,3,2
How do you use a factors trees to find the prime factorizationof 114?
114 57,2 19,3,2
How do you find prime factors for 50?
Use a factor tree. 50 25,2 5,5,2
How do you use a factors trees to find the prime factorization of 44?
44 / 222 / 21144 = 22111 ■
