63
Any multiple of 63.
Sixty-three.
7 and 9 are both divisible by one. 7 and 9 are both prime numbers, meaning the factors are 1 and themselves. The factors of 7 are 1 and 7. The factors of 9 are 1 and 9.
7 is a prime number but 9 is a composite number
6*9=54 so they both go into it evenly, but the lowest number is 18.
7
7 & 9 only have one factor in common: 1. So the number which is a multiple of both is 7 x 9 = 63.
The highest number that both 63 and 14 go into is infinity. They go into infinity an infinite number of times (as does every other number). I'm not sure if you have asked the right question, but if you have then the answer is infinity. If, however, you meant, "what is the highest common factor of both 63 & 14?", then the answer is 7. 63 = 9 * 7 and 14 = 2 * 7.
The answer is 1 thats the only number that can go into 7 and 9
The LCM of 9, 7 and 6 is 126
There is no such even number.
