143 is not prime - we can see this because it is 1 less than a square. x^2-1 = (x+1)(x-1), and for 143, x=12. Thus, 143=11*13.
Prime factorization:143 = 11 x 13231 = 3 x 7 x 1111 x 13 x 3 x 7 = 3003 (the LCM of 143 and 231).
3 x 143 = 429
13x11=143 Answer:143
11 x 13 = 143
No because 143 doesn't have any other factors other than 143 or 1. ============================================= Another contributor contributed: Yes. 143 = 13 x 11
x/11 = 13 Multiply both sides by '11' Hence 11x /11 = 11 x 13 = 143 On LHS '11' cancels down Hence x = 143 The answer is 143/11 = 13
143
Divide by 11 or 13 . 11 x 13 = 143
hcf(33,143) = 11 33 = 3 x 11 143 = 11 x 13 hcf = 11
x = 143
There are 2000 pounds in a ton. So, 143 tons would equal 286,000 pounds (143 x 2000).
