280 = 2 x 2 x 2 x 5 x 7
2*2*2*5*72 x 2 x 2 x 5 x 7 = 280
As a product of its prime factors: 2*2*2*5*7 = 280
yes it is relatively prime
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.

280 = 2 x 2 x 2 x 5 x 7
2 x 2 x 2 x 5 x 7 = 280
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
To find the LCM, first, find the prime factorization of each number:280 = 2 * 2 * 2 * 5 * 7392 = 2 * 2 * 2 * 7 * 7Group the like prime factors (the ones in bold italics)2 * 2 * 2 * 5 * 7 * 7 = 1960
280. You break them down to their prime factorization 5 = 5 7 = 7 8 = 2 x 2 x 2 Multiply each one without repeating a number if it appears in two locations- as in it appears in two different numbers factorization (not a problem here since both 5 and 7 are prime) 5 x 7 x 2 x 2 x 2 = 240
