It's an even number, so it contains a factor of 2. 486/2 = 243. So 486 = 2 * 243 243 is odd so no more factors of 2. Is 243 a multiple of 3? Yes. 243/3 = 81 (no remainder). So 486 = 2 * 3 * 81 81 should look familiar: 9*9 = 81. And we know that 9 = 3*3 Putting it all together: 486 = 2 * 3 * 3 * 3 * 3 * 3 486 = 2 * 3^5 Prime factors are 2 (once) and 3 (five times)

243 * 3465 = 841,995
243 * 4 = 972
243 * 3.14 = 763.02
3x81=243
243 * 82 = 19,926
9 times 27 equals 243.
38 goes into 243 6.39 times.
243 / 5 = 48.65 * 48.6 = 243
243 multiplied by 106 is 25,758
243 x 3 = 729
243/6 = 40.5
