[00:00:00]How to find HCF of 12 and 16 by using prime factorization method? So, in first step, I'll just find the factor of 12 by using prime number. 2 * 6 = 12.

[00:00:14]2 * 3 = 6.

[00:00:16]And 3 * 1 = 3.

[00:00:19]So, write the factor of 12 here.

[00:00:21]12 equal to this are the factor. So, 2 into 2 into 3.

[00:00:27]Now, I'll find the factor of 16.

[00:00:31]2 * 8 = 16.

[00:00:35]2 * 4 = 8.

[00:00:37]2 * 2 = 4.

[00:00:40]And 2 * 1 = 2.

[00:00:42]So, write the factor of 16 here.

[00:00:45]Oh, so write here 2 into 2 into 2 into 2.

[00:00:50]Now, I'll find the HCF of 12 and 16.

[00:00:59]Now, you see the common factor.

[00:01:02]So, 2 is common here.

[00:01:04]So, write here 2 into Again, one more 2 you have common. So, this also you write here.

[00:01:11]Now, you do multiply. 2 and 2 multiply is 4. 2 * 2 = 4. So, this is the HCF of 12 and 16.
