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
280 = 23 x 5 x 7
Answer: 70% Solution Method 1: 1 - (84 / 280) = .7 .7 * 100 = 70% Check: 280 * .7 = 196 280 - 196 = 84 Solution Method 2: 280 - 84 = 196 196 / 280 = .7 .7 * 100 = 70% Check: 280 - (280 * .7) = 280 - 196 = 84 === Previous (incorrect) answer: 84/280=.33333 100-33.333=66.666 66.666% decrease you can check your work by multiplying 84 by 3 since .3333 is 1/3rd and you get 280
23 x 5 x 7

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
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
