A number's prime factorisation is 2^{3} X 3^{2} X 5^{2}
Is the number even or odd? Explain your reasoning.
Name four other factors of this number, other than 2, 3 and 5.

Even. As 2 is a even number, any numbers multiplied by 2 will also be a even number so 2^3 is a even number. Any numbers multiplied by an even number will also give an even number so the answer is a even number. 4 other factors are 6, 10, 15 and 4

The number is even. 2multiplied by 2 or more 2's is always an even number and also any number. An even number multiplied by an odd number and the answer is always a even number. Thus, the answer is even.

The four other factors of this numbers are 4, 6, 8, 10

since 2 is an even number, 2 to the power of any other number would be an even number as well.

ReplyDeletea negative number to the power of a positive number is always a positive number so 3^2 x 5^2 is a positive number.

since a positive x a positive = positive, 2^3 x 3^2 x 5^2 is an even number.

four other factors :

450

300

900

360

2 is an even number so when a number is multiplied by2, the answer will be an even number and the other factors are 600,300, 900 and 360
