A composite number is a number that can be divided evenly by more numbers than 1 and itself. The number 72 can be evenly divided by 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72, with no remainder. Since 72 cannot be divided by just 1 and 72, it is a composite number.
Is 72 composite or prime?
Is 72 a prime number? “No, 72 is not a prime number.” Since 72 has more than 2 factors i.e. 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72, it is a composite number.
Is 19 prime composite or neither?
Is 19 a prime number? Yes. The only factors of 19 are 1 and 19, so 19 is a prime number. That is, 19 is divisible by only 1 and 19, so it is prime.
How to find the prime factors of 72 by?
