Their HCF is 8
They are 15 and 2145 respectively
The HCF is 20.
The GCF is 28.
The GCF is 15 so far.
hcf = 15 lcm = 3510 270 = 2 x 33 x 5 195 = 3 x 5 x 13 hcf = 3 x 5 = 15 lcm = 2 x 33 x 5 x 13 = 3510
The Highest Common Factor (HCF) of 165, 195, and 285 is the largest number that divides all three numbers evenly. To find the HCF, we first factorize each number: 165 = 3 x 5 x 11, 195 = 3 x 5 x 13, and 285 = 3 x 5 x 19. Then, we identify the common factors among the three numbers, which are 3 and 5. Therefore, the HCF of 165, 195, and 285 is 15 (3 x 5).
Well, isn't that a lovely question! The Highest Common Factor (HCF) is like finding the biggest brush to paint a beautiful picture. When we look at 280 and 180, we can see that their factors are 1, 2, 4, 5, 10, 20, 14, 28, 56 for 280 and 1, 2, 3, 4, 6, 9, 12, 15, 18, 30, 45, 60 for 180. The largest number that appears in both sets is 20, so the HCF of 280 and 180 is 20. Just like adding a touch of white to make colors brighter, finding the HCF helps us simplify and see the beauty in numbers.
