Any number whose prime factorization includes 5 and 23 is a multiple of 115. 115 = 5 x 23 230 = 2 x 5 x 23 345 = 3 x 5 x 23 460 = 2 x 2 x 5 x 23 575 = 5 x 5 x 23 690 = 2 x 3 x 5 x 23
5 × 23 × 2 = 230
1 x 115, 5 x 23, 23 x 5, 115 x 1
5 = 5 24 = 23 x 3 8 = 23 LCM = 5 x 23 x 3 = 120
So you have: (x - 5)/7 = x - 23 (multiply both sides by 7) x - 5 = 7x - 161 (subtract x and add 161 to both sides) 156 = 6x (divide both sides by 6) x = 26 Mistakes (below): 5 - x = subtract x from 5, but we want to subtract 5 from x. the answer/7 = 23 less than x = subtract 23 from x = x - 23 if you tried to ask 5-x=__/7= 23 the answer is 166 5-x=__/7=23 first you would multiply 7 x 23 which is 161 5-x=161 second you would add 5 on both sides since you are subtracting in the problem 5+5-x=161+5 third you add 161 and 5 together and you would get 166 so x=166
1 x 115, 5 x 23 | 23 x 5, 115 x 1
1 x 115, 5 x 23, 23 x 5, 115 x 1 = 115
345 3 x 115 3 x 5 x 23 345 = 3 x 5 x 23
The prime number for which 23 is a factor is 23.
1 x 115, 5 x 23, 23 x 5, 115 x 1 = 115
1610. 70 = 2 x 5 x 7 115 = 5 x 23 lcm = 2 x 5 x 7 x 23 = 1610
3240 = 23 x 34 x 5
