How do you find the gcf of 73 and 127?
Find the factor pairs of each number. The greatest factor in common is the GCF. A hint, the definition of a prime number is a number with only two factors: 1 and itself.
How do you find whether a number is a perfect square by using its prime factors?
In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.In the prime factorisation of the number, each factor must appear an even number of times.
What is the GCF of 36 24 18?
Find the factors of all three numbers and then find the largest number that is in each list: i.e. the factors of 18 are 1, 2, 3, 6, 9, 18. So for example, to find the greatest common factor of 21, 28 and 42, find the factors of each: Factors of 21 are 1,3,7,21 Factors of 28 are 1,2,4,7,14,28 Factors of 42 are 1,2,3,6,7,14,21,42 The highest number that is in all three lists is 7. Therefore, 7 is the greatest common factor. Note: A factor is a number that divides evenly into the number. So, 2 divides evenly into 8 so 2 is a factor of 8. 3 divides evenly into 9 so 3 is a factor of 9, etc.
What array can you make to show the factors of 16?
You can create an array with some elements, get the factors of a number (such as 16), and while you get each of the factors, place the factors in the array. Every time you find a factor, divide the number by this factor before you search the next factor (to avoid getting the same factor over and over again).
Find all the factor of the number 36?
1,2,3,4,6,9,12,18 are the factors of 36.
How do you find the gcf of 73 and 127?
Find the factor pairs of each number. The greatest factor in common is the GCF. A hint, the definition of a prime number is a number with only two factors: 1 and itself.
What are concepts to finding the greatest common factor?
-- List all factors of the first number. -- List all factors of the second number. -- If there are more than two numbers, list all factors of each one. -- Find the set of factors that are on every list. -- Find the greatest factor in the set.
How do I use 16 as factor trees to find the prime factors of each number?
16 8,2 4,2,2 2,2,2,2
How you know that any numbers have at least one common factor?
You can start by listing out each number's factors. Then, when you find at least one common factor, that is your answer!
What does a factor tree find?
All factors of a number
What is the greatest common factor of 121 and 132?
121: 11-11 132: 2-2-3-11 Great common factor: 11 Method(s) used: # (used) The method to find the greatest common factor of numbers is to find the prime factorizations of each one, select all matching prime factors, and then multiply. # An alternative method is to find all of the factors of each, and then select the greatest number that appears in each list. # The final method only applies to some numbers; if one of the number is a factor of the other, then that number is the greatest common factor. This is because all numbers are factors of themselves, and that is their greatest factor. If it is also a factor of the other number, then it is definitely the greatest common factor.

What is the greatest common factor of 196 and 1078?
196: 2-2-2-2-11 1078: 2-7-7-11 Greatest common factor: 22 Method(s) used: # The method to find the greatest common factor of numbers is to find the prime factorizations of each one, select all matching prime factors, and then multiply. # An alternative method is to find all of the factors of each, and then select the greatest number that appears in each list. # The final method only applies to some numbers; if one of the number is a factor of the other, then that number is the greatest common factor.

If you know a factor of a number can you find another factor explain?
Factors come in pairs. If you know one factor, divide it into the number. The answer will be another factor.
What is the greatest common factor of 125 and 50?
GCF of 50 and 125 is 25.First off you will want to figure out all of the factors of each number:125: 1,5,25,125 50: 1,2,5,10,25,50Ok, now that you have all of the factors of each number, you want to find the greatest common factor. This means that you want find the biggest number that is a factor of both of the two numbers.Both 5 and 25 are factors of these two numbers. Now you have to figure out which one is the biggest. 25 is the biggest and that is your answer.
Find the smallest integer k such that 756k is a perfect cube?
Factor 756 into prime factors. Then add additional prime factors, such that each prime factor occurs a number of times that is a multiple of 3. The product of the additional prime factors is "k".
