It is 3 time 7 = 21
It is: 3*7 = 21
21
Product of the two prime numbers is the LCM. For example 3, 7 have 21 as LCM
21 = 3x7, and so is not prime, as it can be expressed as the product of multiple prime numbers
21 is the product of two prime numbers, three and seven. A prime number is defined as a number divisible only by one or itself. So ... NO ... 21 is not a prime number.
3 and 7 are prime numbers whose product is 21.
As a product of its prime factors: 3*7 = 21
It is: 3*7 = 21
if you mean their product is 21, then 7x3=21
21
Product of the two prime numbers is the LCM. For example 3, 7 have 21 as LCM
It is simply: 3 times 7 = 21
21 = 3x7, and so is not prime, as it can be expressed as the product of multiple prime numbers
21 is the product of two prime numbers, three and seven. A prime number is defined as a number divisible only by one or itself. So ... NO ... 21 is not a prime number.
13 is prime so it is not the number. 15 is the product of 3 and 5, two prime numbers, so it fits the conditions. 17 is prime so it is not the number. 19 is prime so it is not the number. 15 is the only odd number between 11 and 21 that fits the conditions. However, if 21 is included in the range, it also is the product of two prime numbers: 3 x 7.
3 and 7 are the prime numbers because they cannot be divided by any number other than themselves and 1because 3+7 = 10 (Sum)and 3x7 = 21 (Product)
To express 63 as a product of prime numbers, you start by dividing it by the smallest prime number, which is 3. Dividing 63 by 3 gives 21, and dividing 21 by 3 again gives 7. Since 7 is a prime number, the prime factorization of 63 is (3^2 \times 7).
