Is odd numbers prime numbers?
prime number is a number that could only be divided by itself and one. odd numbers are naturally not divisible by 2 but odd numbers can be divisible by other numbers. one example is 15. 15 is divisible by itself and one but also by 3 and 5.
What are multiples of 3 and 5?
Since both 3 and 5 are prime numbers, only numbers that are multiples of its product are the numbers that are divisible by both. 15 is the LCM of 3 and 5 and hence all multiples of 15 are divisible by both 3 and 5
Would the quotient of two evenly - divisible odd numbers never prime?
No. 15 divided by 5 = 3
Is every odd number is prime or not?
No, there are many odd numbers that are not prime: 9, 15, 21, 25, 27, etc. However, 2 is the only even number that is prime, since all other even numbers are divisible by 2.
Which of these numbers are prime number 72 87 42 59?
You can elimate the even numbers 72 and 42 right away because the only even prime number is 2. Using the divisibility rules, you can eliminate 87; 8 + 7 = 15, which is divisible by 3, which means 87 is divisible by 3. 59 is the prime number.
