It is LCM(23, 4) = 92.
To find a four-digit number divisible by both 23 and 9, we first determine the least common multiple (LCM) of the two numbers. The LCM of 23 and 9 is 207. The smallest four-digit number is 1000, and the largest is 9999. Dividing 1000 by 207 gives approximately 4.83, so the smallest four-digit number that is a multiple of 207 is 5 × 207 = 1035.
418 multiplied by 23 is 9,614
23 is not divisible by 7.

2520. The number needs to have a prime factorization of 23*32*5*7=2520.
Multiply the last digit by 7. Subtract that number from the remaining digits. If that number is divisible by 23, then the original number is divisible by 23.
23 is a prime number so it is not divisible by 3. It is only divisible by 1 and 23. Dividing 23 by three gives the result of 7.6r
