How do you use arrays or area models to find factor pairs?
I am not sure what you mean with "area models". As for an array, one simple way to use it is to try out different factors in a loop; every time you find a factor, you write the factor to the next array element.
What is the greatest common factor of 91 and 77?
To identify the GCF of 91 and 78, you first need to break these down into their prime factors: 91 = 7x13 78 = 2x3x13 The next step is to identify any common prime factors. In this case, both numbers have 13 as a prime factor. Thus the greatest common factor of 91 and 78 is 13.
How is the number of rectangles you can build related to factors of a number?
If you can compile a complete list of all different rectangular models with sides of integer length for a number then their lengths and breadths represent its factors.
How do you factor a polynomial if their are more than one factors?
Factor it once, and then factor the factors.
What are the greatest common factors of 9 and 25?
Answer:The only common factor of 9 and 25 is 1.The greatest common factor of 9 and 25 is 1.Because 1 is the only common factor, the numbers are relatively prime.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 9 are 1, 3, and 9.The factors of 25 are 1, 5, and 25.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The common factors and greatest common factor can also be calculated by identifying the common prime factors and multiplying them together to identify the greatest common factor, and then taking all the factors of it to determine the common factors.The prime factors of 9 are 3 and 3.The prime factors of 25 are 5 and 5.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
How does the number of factors determine the number of different rectangular arrays that can be made for given number?
Each factor pair is an array.
What are arrays possible for number 7?
identify two composite numbers that each have 8 as a factor
What are the factors of a non-rectangular number?
1 is a non-rectangular number. The only factor of 1 is 1.
What is difference between Bac arrays and DNA arrays?
BAC (Bacterial Artificial Chromosome) arrays are a type of DNA arrays. BAC arrays are usually used for a technique called array CGH (Comparative Genomic Hybridisation) which is used to identify gross deletions or amplifications in DNA (which for example is common in cancer). DNA arrays include BAC arrays but also oligo, cDNA, and promoter arrays. Oligo and cDNA arrays are typically used for gene expression analysis (looking to see how heavily expressed each gene is). Oligo arrays can also be used for SNP (single nucleotide polymorphism) analysis. Promoter arrays are used to identify transcription factor binding sites.
What is all the common factors of 378 and 100 and identify the greatest common factor?
100 has factors 1,2,4,5,10,20,25,50,100. 378 has factors 1,2,3,6,7,9,14,18,21,27,42,63,126,189,378. 2 is the greatest common factor.
What is a diagram used to identify the prime factors of a composite number?
factor tree

How will making an array help someone find factors in a number?
The numbers of rows and columns in a rectangular array form a factor pair for that number.
What is the greatest common factor of 91 and 77?
To identify the GCF of 91 and 78, you first need to break these down into their prime factors: 91 = 7x13 78 = 2x3x13 The next step is to identify any common prime factors. In this case, both numbers have 13 as a prime factor. Thus the greatest common factor of 91 and 78 is 13.
How do you identify a correct prime factorization?
First, make sure all the factors are, in fact, prime. Then make sure that the product of all the factors is the number you wanted to factor.
How do you find the sum of the distinct prime factor of a number?
Find the prime factorization. Identify the distinct prime factors. Add them up.
How is the number of rectangles you can build related to factors of a number?
If you can compile a complete list of all different rectangular models with sides of integer length for a number then their lengths and breadths represent its factors.
