Answer:

We can find the highest common factor of a number by listing down all the factors of that number. The greatest factor from that list is the highest common factor.

Question -:

How to find HCF of two numbers

Explanation -:

We can find the HCF of any numbers using three methods -:

  • Common Factor
  • Prime Factorisation
  • Division Method

[tex] \small \orange{\bf{ Step \: 1 :}}[/tex]

  • Find all factors of the given number

[tex] \small \blue{\bf{ Step \: 2 :}}[/tex]

  • Find the common factor

[tex] \small \purple{\bf{ Step \: 3 :}}[/tex]

  • Find out the highest common factor from the common factor . The highest common factor is the HCF of the number.

[tex] \small \underline{\underline{\bf{ Prime \: Factorisation }}}[/tex]

[tex] \small \orange{\bf{ Step \: 1 :}}[/tex]

  • Find the prime factor of the given number by division method.

[tex] \small \blue{\bf{ Step \: 2 :}}[/tex]

  • Find out the common prime factor.

[tex] \small \purple{\bf{ Step \: 3 :}}[/tex]

  • The product of the common prime factor gives the HCF of the number.

[tex] \small \underline{ \underline{\bf{ Division \: Method}}}[/tex]

[tex] \small \orange{\bf{ Step \: 1 :}}[/tex]

  • Divide the greater number by the smaller number. By the remainder in step 1 divide the smaller number

[tex] \small \blue{\bf{ Step \: 2 :}}[/tex]

  • By the remainder in Step 2 divide the remainder obtained in Step 1.

[tex] \small \purple{\bf{ Step \: 3 :}}[/tex]

  • Complete in the same way till no remainder is left.
