Any multiple of 360 between 1080 and 9720 inclusive.

No. While 4 is a factor of 40, it is not a prime number.

i im a multiple of 3. I am between 40 and 50. who could i be.

To determine the least common multiple of two numbers, determine the prime factors of both number. Then, determine the prime factors they have in common. Multiply all their prime factors together and then divide by the prime factors they have in common. The prime factors of 14 are 2 and 7. The prime factors of 40 are 2, 2, 2, and 5. The common prime factors are a single 2. Therefore, the least common multiple is 2 x 7 x 2 x 2 x 2 x 5 ÷ 2 = 7 x 2 x 2 x 2 x 5 = 280.

There are two prime numbers between 30 and 40 - these are 31 and 37.

37

The numbers 31 and 37 are prime.

The prime factorization of 32 is 2x2x2x2x2 or 25. The prime factorization of 40 is 2x2x2x5 or 23x5. For a number to be a multiple of a given number the multiple must have the entire prime factorization of that number in is. So a multiple of 32 must contain 2x2x2x2x2 or 25 . Likewise a multiple of 40 must contain 2x2x2x5 or 23x5. The least number that this could possible happen with must have 5 factors of 2 and one factor of 5 (the highest exponent on each individual prime factor). Thus the LCM is 2x2x2x2x2x5 or 25x5 Which is 160.
