Divide all terms by 5 and so x^2+6x-55 = (x+11)(x-5) when factored
4/5 * 55 = 44. To solve, multiply 55 x 4. Divide by 5. Answer: 44
55 Divide by 5. 11,5 Stop. All the factors are prime. 5 x 11 = 55
800 Divide by two. 400,2 Divide by two. 200,2,2 Divide by two. 100,2,2,2 Divide by two. 50,2,2,2,2 Divide by two. 25,2,2,2,2,2 Divide by five. 5,5,2,2,2,2,2 Stop. 2 x 2 x 2 x 2 x 2 x 5 x 5 = 800
5 x 11 = 55 2 x 5 x 7 = 70 2 x 5 x 7 x 11 = 770, the LCM
Factors of 6 : 1, 2, 3, 6 Factors of 25 : 1, 5, 25 Factors of 55, 1, 5, 11, 55 Common factor pairs = 5 (from 25 and 55) LCM = Product of all numbers divide by the common factors LCM = (6 x 25 x 55) / (5) = 1650
The greatest common factor of 55 (5 x 11) and 105 (3 x 5 x 7) is 5.
550 = 2 x 275 = 2 x 5 x 55 = 2 x 5 x 5 x 11
700 = 2 X 2 X 5 X 5 X 7 The answer is 2, 5, 7
220 = 2^2 x 5 x 11 2 x 2 x 5 x 11 = 220
