A number is a multiple of 7623 if it's a multiple of 7, 9 and 121 at the same time 7623 = 3^2 x 7 x 11^2 = 9 x 7 x 121 A number is a multiple of 7 if the difference between twice the last digit and the rest of the number is a multiple of 7 A number is a multiple of 9 if the sum of the digits is a multiple of 9 A number is a multiple of 121 if the difference between 12 times the last digit and the rest of the number is a multiple of 121 For example 15246 is a multiple of 7 because 1524 - 6 x 2 = 1512 and 1512 is a multiple of 7. It's a multiple of 9 because 1 + 5 + 2 + 4 + 6 = 18 and 18 is a multiple of 9. It's a multiple of 121 because 1524 - 6 x 12 = 1452 and 1452 is a multiple of 121. Since it's a multiple of 7, 9 and 121 it means it's a multiple of 7623

The multiples of 2, 3 and 7 is 42.
It is: (3*7)+2 = 23
The number is 42 or any multiple of 42. All of the qualifiers mean the same thing : the number is a multiple, of 2, 3, and 7. Using the Least Common Multiple: 2 is prime, power is 1 3 is prime, power is 1 7 is prime, power is 1 2 x 3 x 7 = 42
Any multiple of 210.

To find the common multiples of 2, 3, and 7, we first list the multiples of each number: Multiples of 2: 2, 4, 6, 8, 10, 12, ... Multiples of 3: 3, 6, 9, 12, 15, 18, ... Multiples of 7: 7, 14, 21, 28, 35, ... The first common multiple of 2, 3, and 7 is 6, as it is the smallest number that is a multiple of all three numbers. The second common multiple is 12, as it is the next number that is a multiple of all three numbers.
The least common multiple of 2, 3 and 7 is 42.42
