The greatest factor of a number is the number itself.
No. Here are some numbers that have 13 as a factor, but do not have 5 as a factor: 26, 39, 52, 78, 91, 104, and 117.
1180 is a composite number because it has more than two factors whereas prime numbers have only two factors.

 To calculate the least common multiple (lcm) of decimals (integers)  and fractions you first need to calculate the greatest common  divisor (gcd) of two integers:    int gcd (int a, int b) {   int c;   while (a != 0) {   c = a;   a = b % a;   b = c;   }   return b;  ...
No, it is not a prime number.

97 is a prime number so it's only factors are 1 and 97.
13 + 11Prime numbers are numbers only have 2 factors - 1, and itself.
No.The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24 because they all can be divided into 24 with no remainder.
Yes because it has only two factors which are itself and one
Determine the prime factors of both numbers.400 = 2 x 2 x 2 x 2 x 5 x 5 = 24 x 52120 = 2 x 2 x 2 x 3 x 5 = 23 x 3 x 5The common factors are 23 and 5 : The highest common factor is 23 x 5 = 40.Common factors are formed from the individual common factors together with any combination of those factors...
There are several combinations, but this is one: 23 + 29 = 52.
The number one is far more special than a prime! It is the unit (the building block) of the positive integers, hence the only integer which merits its own existence axiom in Peano's axioms. It is the only multiplicative identity (1.a = a.1 = a for all numbers a). It is the only perfect nth power for...

They are: 3, 7 and 11
15 and 16 if you add them. 40 and 9 if you subtract them. 1 and 31 if you multiply them. 62 and 2 if you divide them.
The term originated from the Latin word primus, meaning first in importance. Prime are the important main ingredient of numbers, for every number greater than one is either a prime or a product of primes.
Divide by two until you get to three. 2 x 2 x 2 x 2 x 2 x 3 = 96

The multiples of 18 are 3^2 and 2, while the multiples of 32 are  2^5.
The LCM of 6, 9 and 15 is 90.
This one doesn't work. The LCM of 6 and either 32 or 96 is 96, but the GCF is 2.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 30, 42, 48, and 60...

Suppose not. Let p be prime and n = Sqrt[p]. Since p is an integer, if n is rational, then n is also an integer. So we have n.n = p. But since p is prime, only 1 and p divide p. -><- therefore n must not be rational
Terms in polynomials are simply separated by a plus or minus sign.  For example, if you had: x+12x, that would be a binomial (two  terms). A trinomial is when the expression has three or more terms,  7x+12x-6x.
4x + 3y + 3 = 4 ----> 4x = 1 - 3y ----> x = 0.25 - 0.75y  ----> 3y = 1 - 4x ----> y = (1/3) - (4/3)x

All prime numbers are going to be deficient, because remember that a prime number's only factors are one and itself. To find if its deficient or abundant, you'd add up all of its factors, excluding itself. If its only other factor beside itself is one, that's obviously less than the number, and...

Express every number in terms of its prime factors. 16 = 2 x 2 x 2 x 2 = 24100 = 2 x 2 x 5 x 5 = 22 x 52The LCM is the product of the highest power of each prime factor.The LCM of 16 and 100 is therefore 24 x 52 = 16 x 25 = 400
