use divisibility rules to find at least four factors of the number 19
Yes. 312 / 3 = 104Because, using your divisibility rules you know that the sum of the numbers (3+1+2) is 6 which is a multiple of 3. threfor you can say, that is does devide by three.
It isn't worthwhile to invent or memorize complicated divisibility rules for lots of numbers. Just carrying out the divisions is faster in most cases.
Any of its factors
You can easIly figure this out by using the fact that all even numbers are Divisible by 2. Because 312 is even it to Is also divisible by 2. Because 312 can be divided by mOre than itself and one, which is what a prime number is, it is composiTe.

2*2*2*2*3*13=312
Any of its factors
312 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 16 factors of 312 are 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, and 312.The proper factors of 312 are 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, and 156 or,if the definition you are using excludes 1, they are 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, and 156.The prime factors of 312 are 2, 2, 2, 3, and 13. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The 3 distinct prime factors (listing each prime factor only once) of 312 are 2, 3, and 13.The prime factorization of 312 is 2 x 2 x 2 x 3 x 13 or, in index form (in other words, using exponents), 23 x 3 x 13.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
