number of prime numbers which are in the seven times tables: 1 prime numbers are in the seven times tables: 7 only
Yes. Every prime number appears in its own times table. But it does not appear in any other.
Because they are tables of the numbers that are the result of "times"-ing a number.
4,8,12,16,20,24,28,32,36,40,44,48,52,56,60 7,14,21,28,35,42,49,56,63,70,77,84,91,98,105
Work It Out By Drawing A Grid, Eliminate the 2 Times Tables, Then 3, Then 5, Then 7, Then 11, Then 13, And All The Primes, And Your Be Left With The Higher Prime Numbers :D
41 x 3 = 123, Quite basic actually.
No. The 7 times table goes like this 7 14 21 28 35 42 49 56 63 70 77 84 so no 40 is not in the 7 times tables but there is 2 numbers in the 7 times tables that is in the 40s.
the numbers in the 4 times tables up to 12 are: 4,8,12,16,20,24,28,32,36,40,44, and 48the numbers in the 5 times tables up to 12 are:5,10,15,20,25,30,35,40,45,50,55, and 60
55 and its multiples. 1, 5, and 55 are all in both the 5 times and 11 times tables.
No numbers besides itself and 1 go into it evenly. The most common numbers to check are 2,3,4,5,6,9, and 10. THe rest you can figure out with times tables.
Multiples of 16.
Think of the definition of a prime number: It has no divisors other than itself and 1 so it cannot be a multiple of any other numbers.
all of the numbers in the 15 times tables and 3 and 5
