Question

Maritza remembers her pin because it is the product of consecutive prime numbers that is between 1000 and 1500. What is her pin

Answer 1

Find the pin number of Maritza which is between 1000 and 1500.
Find the 2 consecutive prime numbers that the product is between the given ranges.
=> Square root of 1000 = 31.6
=> Square root of 1500 = 38. 7
Now, we have the square root value of both number ranges. The only consecutive prime numbers that we have is 31 and 37 that is in 31.6 and 38.7.
=> Let us now find the product of 2 consecutive prime numbers
=> 31 x 37
=> 1147
1147 is more than 1000 but less than 1500. Thus, the pin number of Maritza is 1147.
