To find the prime factorization start with any two factors of 198 and keep factoring the composite factors until all factors are prime. 198 2 x 99 2 x 3 x 33 2 x 3 x 3 x 11 = 198
Prime factors of 99 in exponents: 32 and 11 Prime factors of 18 in exponents: 2 and 32 Mutiply all the highest prime factors: 2*32*11 = 198 which is the least common multiple of 99 and 18
132 = 2 * 2 * 3 * 11 = 22 * 3 * 11198 = 2 * 3 * 3 * 11 = 2 * 32 * 11
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.Since 198 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 198 is 198.You need at least two numbers to find a GCF.
3 x 3 x 7 x 13 = 819
