135 is not prime. 135 = 3 * 3 * 3 * 5135 is a composite number because its factors are:1x1353x455x279x151, 3, 5, 9, 15, 27, 45, and 135.*NOTE: All numbers that have a 0 or a 5 in it are composite, except 5 because they will always have a third factor, 5.
45
To any set that contains it! It belongs to {30}, or {45, sqrt(2), 30, pi, -3/7}, or all whole numbers between 23 and 53, or multiples of 5, or square roots of 900, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
it is 3 numbers all together and they are 25, 36 and 49I hope this helps you
