Because any number that ends with those numbers can be divided by a number. For example, 10 can be divided by 2 and 5, 4 can be divided by 2...
However, 2 is a Prime number; it's just numbers that END with 2 that aren't prime, like 12. 5 is exactly like 2, but a number that ends with 5 can be divided by 5.
No prime numbers end in 0. 130 is a composite.
My Code: ======================================… >> disp('input a pair of natural numbers, N and M with M>N'); N=input('N='); M=input('M='); for j=0:(M-N) Prime=1; for i=2:((N+j)/2) if mod((N+j),i)==0 Prime=0; break end end if Prime==1 disp('This is a Prime Number'); else disp('Not Prime'); end end
Cls input "enter the no. You want to check", a if a <=0 then print "only natural nos allowed" if a <=0 end let m = a - 1 for i = m to 2 step -1 if a mod i = 0 then print "not prime" if a mod i = 0 then end next i print "prime" end
1 is a prime number, but 0 is neither a prime number nor a composite number.
To be relatively prime you must relate the number to another number. 125 is 5³ so it is relatively prime to all numbers that are not multiples of 5 (do not end in 0 or 5)
No prime numbers end in 0. 130 is a composite.
Any number that isn't prime.
No. 0 is not a prime number. 2 is the lowest prime number

1 is a prime number, but 0 is neither a prime number nor a composite number.
0 and 1 is not prime number because the prime number can only be divided by the number 1 and itself.
To be relatively prime you must relate the number to another number. 125 is 5³ so it is relatively prime to all numbers that are not multiples of 5 (do not end in 0 or 5)
Zero is not a prime number.
No, like 1, 0 is neither prime nor composite.

Lots of prime numbers have zeros in them. 101, 103, 107 and 109 are all prime numbers. Prime numbers can't end in zero. Numbers that end in zero are multiples of ten and have too many factors to be prime numbers.
