The prime factors of 84 are 7, 3 and 2. When 7 is multiplied by 3, 2 and then 2 again, the result is the original 84.
Continue ReadingPrime factors refer to the factors of a number that are also prime numbers. Prime numbers are the numbers that are greater than one that only have factors of themselves and 1. Dividing 84 by the smallest prime factor yields 42, which yields 21 when divided by 2 again. Finally, 21 can be divided the its smallest prime factor, 3, to yield 7, which is also a prime number.

Full Answer >The prime factors of the number 24 are 2 x 2 x 2 x 3 , or 2 to the 3rd power x 3. Two and three are prime numbers, and when three twos and a three are multiplied together, the product is the given number, which is 24.
Full Answer >To find the greatest common factor of two or more integers, the common prime factors of each number are multiplied together. The result is the greatest common factor of those two or more integers. If there are no common prime factors of the integers, then the greatest common factor is 1.
Full Answer >The prime factorization of 72 is 2^{3x} 3^{2}, or 2 x 2 x 2 x 3 x 3. The prime factorization of a number involves determining the factors of a number that are also prime numbers and multiply together to equal the original number.
