2*2*2*5*72 x 2 x 2 x 5 x 7 = 280
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.
As a product of its prime factors: 2*2*2*5*7 = 280
yes it is relatively prime
280 = 23 x 5 x 7
23 x 5 x 7
280 140,2 70,2,2 35,2,2,2 7,5,2,2,2
23 * 5 * 7
It is: 2, 2, 2, 5 and 7
2 x 2 x 2 x 5 x 7 = 280
280 = 2 x 2 x 2 x 5 x 7
2*2*2*5*72 x 2 x 2 x 5 x 7 = 280
2 x 2 x 2 x 5 x 7 = 280, the LCM
The prime factorization of 280 is: 2 x 140 2 x 2 x 70 2 x 2 x 2 x 35 2 x 2 x 2 x 5 x 7. The three prime factors of 280 are 2, 5, 7.
2 x 2 x 2 x 3 x 3 x 3 x 5 x 5 x 5 = 27,000
