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: ...
which exactly divides two or more given numbers is the common factor of the given numbers. Infactorization, 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 ...
Theprime factorsof a number are the 'prime numbers' that are multiplied to get the original number. For example, 2 and 5 are the prime factors of 20, i.e., 2 × 2 × 5 = 20. We know that the factors of a number are the numbers that are multiplied to get the original number. ...
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...
