A number m is formed by writing all the prime numbers between 0 and 10 in an ascending order. Another number n is formed by writing all the square numbers between 0 and 10 in a descending order.

Question

(a) Find m - n;
(b) Express (m - n) as a product of its prime factors.

Answer 1

surely you know the primes and squares.
So, write them in order to form large-ish numbers.
Then subtract and factor

Answer 4

M=2,3,5,7=2357. N =4,9=94 .2357-94=2263. 2263=31,73 are the prime factors

Answer 5

2357-149=2208

1is also a square number

Answer 6

2208

Answer 7

Yes, you are correct. There is an error in the previous message. The correct answer is:

M = 2, 3, 5, 7 = 2357
N = 9, 4, 1 = 941

Then, M - N = 2357 - 941 = 1416

To factorize 1416, we can first divide it by 2 to get:

1416/2 = 708

Then, we can factorize 708 as:

708 = 2 x 2 x 3 x 59

Therefore, we have:

M - N = 1416 = 2 x 2 x 3 x 59.
