Example: Find the HCF of 126, 162 and 180. Solution: By prime factorisation, we can write the given numbers as; 126 = 2x3x3x7 162 = 2x3x3x3x3 180 = 2x2x3x3x5 Taking out the common factors of 126, 162 an d180, we get: ...
the common prime factors with the smallest powers. For example, let us find the HCF of 12 and 18. The prime factorization of 12 = 22× 31, and the prime factorization of 18 = 21× 32. Among the common prime factors, the product of the factors with the smallest powers is 21× 31=...
In factorization, we intend to find the factors of a given number. Now what to do if we had to find the common factor between two or more numbers. This is where the concept of HCF comes into play. The HCF or Highest Common Factor of two or more numbers is the greatest common factor...
Factors of a given number are finite. We have seen in the previous property that the factors are 18 are 1, 2, 3, 6, 9 and 18 and there cannot be a factor that is greater than the number 18 itself. Since the number is finite, therefore, it will have finite numbers of factors only...

So, the prime factors of 100 are written as2 x 2 × 5 x 5 or 22x 52, where 2 and 5 are the prime numbers. It is possible to find the exact number of factors of a number 100 with the help of prime factorisation. The prime factor of the 100 is 22x 52. ...
Prime numbers arenatural numbersgreater than 1, that have only two factors, 1 and the number itself. A number can be a prime number if it is a non-zerowhole number. Prime factorizationis a method to find prime numbers. How to Find Prime Numbers up to 100?
Question 3: How do you find the prime factors of a number? Answer: The prime factors of a number refer to the entire prime numbers that, when we multiply together will equal the original number. Thus, one can find the prime factorization of a number by making use of a factor tree and...
