Isn't 28 a factor of 42

[@agnesfrempong9720]

Interesting to me

[@HoiChungTam]

@@adarshsathiyan-kv8wm no is not .28 + 28 =56

[@Katie_1501]

I love how your videos have the words in different colors to show the different parts, like in your lcm video where u showed a common factor and the lcm and the words were different colors in the lcm part to show it’s difference, it’s really cool for me to see!

[@Madmark50484]

I think I spotted an error in your video, @4:25 "find the HCF of 132 and 420" you then have "the prime numbers of 28 and 42" instead 132 and 420. The prime numbers listed are that of 132 and 420.

I believe there is a mistake in this video. On the last sum it says find the HCF of 132 & 420, then if gives the prime factors but says of 28 & 42 again.

[@Creative-Learning]

Kindly clear my point. why some teachers tell us the HCF is the Highest common factors in all the common factors while it is the product of the common factors as shown in your video.

[@fireemperorzuko8756]

It literally says in the name, it's the highest common factor of both numbers

[@sexistatheist6464]

The HCF of two numbers is the highest factor that both numbers have in common. What the video demonstrates is that you can also find the HCF of two numbers by multiplying their highest common PRIME factors (i.e. the common factors which are also prime numbers). The factors listed in the video were only the prime factors. They did not include the non-prime factors.

hey, your videos are really helpful thank you! at 4:7 I believe there's a mistake in the animation as it claims the prime factors of 28 are 2*2*3*11. I think the wrong numbers have been written in the working for HCF of 132 and 420

[@GabrielleEarlam]

I saw this too! Is this a kind of exam questions? Might they give us 2 higher numbers to find the HCF but then give 2 smaller prime factor numbers to work it out from?
