21 x 33 x 51 = 270
It is: 21*33*51 = 270
Prime factorization of 270: 2x3x3x3x5 So any one of these factors or combination of these factors will divide exactly into 270. Any number that is not one of these factors or a combination will not. For example, 3x3x3x2=54 so 54 will divide exactly into 270. 270/54 = 5
2 x 3 x 3 x 3 x 5 = 270
3.2
The prime factorization of 270 is2 x 3 x 3 x 3 x 5 or 2 x 3^3 x 52 x 3 x 3 x 3 x 5 = 270
The factorization of a number is a series of numbers that make that number 
The Factors of 270 are: 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135
270 / 1.35 = 200 Therefore, the number that 270 is 135 percent of, is 200.
Well, honey, the Least Common Multiple (LCM) of 18, 81, and 270 is 810. It's like finding the common ground in a messy family reunion - you gotta pick the biggest number that all the others can agree on. So, there you have it, 810 is the magic number that keeps these three troublemakers in line.
It is any number that is not a factor of 270
100 + 270 = 370
