To have 2 5 and 9 as factors means that you also have 3 (subfactor of 9), 6 (2 times 3), 10 (2 times 5), 15 (3 times 5), 18 (2 times 9), 30 (2 times 3 times 5), 45 (5 times 9) and 90 (2 times 5 times 9).  Since all numbers also have 1 as a factor, we already are at 9 other factors, and the smallest number that has all those factors is 90.

The factors of 186 can be found as follows:\n\n186 is even, so 2 is a factor\n186/2 = 93\n\nBoth 9 and 3 are divisable by 3, so 3 is a factor\n93/3=31\n\n31 is prime, so it's the final factor.\n\nI'm not sure how you'll get anything to add up to 46 though, maybe 36?

z=79 because z+100=179.\nj=21 because 179-j=158.\nSo a=9 because j or 21+a=30.

Total 20 nines (2 in 99) are there in 0 to 100.\n\n9, 19, 29, 39, 49, 59, 69, 79, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99

Multiply 12.75 by a conversion factor of 2.54 for an approximation.  It's a little over 32

P = 2W + 2L\nReplace W with 10 and L with 19\nP = 2(10) + 2(19)\nP = 20 + 38\nP = 58 in

9 = 3*3, and 21 = 3*7, so common multiples must have at least two factors of 3, and one factor of 7; ie they must be a multiple of 3*3*7 = 63. Theres only one - 63.\n\nOr you could just list multiples of 21: 21,42,63,84. Only one is a multiple of 9.
