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)
If the least common multiple of two numbers equals the product of the two numbers, then the numbers are relatively prime, that is their highest common factor is 1. For example, the numbers 10 and 21: The lcm is 10 x 21 = 210 They are relatively prime since their hcf is 1.
