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.
The least common multiple (LCM) of 35 and 56 can be found by determining the prime factorization of each number. The prime factorization of 35 is (5 \times 7), and for 56, it is (2^3 \times 7). The LCM is found by taking the highest power of each prime factor, resulting in (2^3 \times 5^1 \times 7^1 = 280). Therefore, the LCM of 35 and 56 is 280.
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
