Answer 1

Hello! It's been a while since I've did LCM and HCF, but I believe your answer is 2.

First, you find the LCM of 12 and 27. This will be 108.

27,54,81,108

12,24,36,48,60,72,84,96,108

Next, you'll want to find the HCF of 24 and 64. This will be 4.

24: 1 · 24, 2 · 12, 3 · 8, 4 · 6

64: 1 · 64, 2 · 32, 4 · 16, 8 · 8

1 , 2 , 4

Finally, you have to find the HCF of 108 and 4. This will result in your answer, 2.

Factors of 108: 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

Factors of 4: 1, 2

1, 2

Hope this helps you. Have a great day! (. ❛ ᴗ ❛.)
