What numbers might be mistaken as prime?

Larger semiprime numbers are often mistaken for prime if their other factor(s) are not obvious. 40477, for instance, might appear prime at first.


What number goes into 68 and 85?

17.68/17= 485/17= 5If you want to find the Greatest Common Denominator (the lowest number that goes into a set of numbers) of two numbers like 68 and 85 or more than two numbers for that matter, you first must find the prime factorization of all the numbers.Prime Factorization means breaking every factor of a certain number down until they are all prime. The best way to find prime factorization is to make a factor tree by starting with the number and breaking each factor pair down further and further. 68/2 gives you the two factors of 2 and 34 (2x34=68) Now, 2 is a prime number so you are done with that. Break down 34 to get 2 and 17 (2x17=34). 2 and 17 are both prime so you can't go any further. Now you have three prime numbers for your factorization (2,2, and 17).Prime factorization of 68= 2x2x17Prime factorization of 85= 5x17(Notice the factorization equal the number)Second, take the factors that they all share and multiply them together. In this case, 68 and 85 only have one shared factor (17) so your Greatest Common Denominator is 17.This method may seem confusing but it helps if your trying to find the GCD of more than 2 numbers. For instance...Find the Greatest Common Denominator of 204, 112, 36, and 48.First find the prime factorization for each:204= 2x2x3x17112= 2x2x2x2x736= 2x2x3x348= 2x2x2x2x3Now find the common factors and multiply them together. They all share:204= 2x2x3x17112= 2x2x2x2x736= 2x2x3x348= 2x2x2x2x3And so you're left with two 2's. Multiply them together to get:2x2= 44 is your Greatest Common Denominator.

What is the greatest common factor of 51 and 85?

The greatest number which divides both 51 and 85 is 17. So, greatest common factor is 17.Alternate method:P.F. of 51 = 3x17P.F. of 85 = 5x17Clearly, from the P.F. of both numbers 17 is the greatest common factor.The GCF is 17.51 and 85's highest common factor is 17.

Is 51 a prime?

No, 51 is not a prime number. A prime number is a number that has only itself and 1 as a factor. 51's factors are 1,3,17, and 51.


How to find a number that equals prime factor s?

All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
