Which is the least common multiple of 4, 9 and 12?
Robert Guerrero
Published Feb 20, 2026
The prime factors of 12 are 2 and 3 (12 = 2² × 3), so we have the factor of 4 that we need, but we need another factor of 3 to get the LCM. 3 × 12 = 36 = 9 × 4 = LCM of 4, 9, and 12. Use J’s LCM operator (*.): The answer is 36. “Civilization advances by extending the number of important operations which we can perform without thinking of them.”
What are the common multiples of 9 and 12?
Common multiples of 9 and 12 are numbers that both 9 and 12 can be divided into evenly with no remainder. To find the common multiples of 9 and 12, we compare the list of multiples of 9 with the list of multiples of 12 to see what they have in common. To create a list of multiples of 9, we multiply 9 by 1, 9 by 2, and so on like this: 9 x 1 = 9
Which is the least common multiple of two numbers?
For example, LCM (2,3) = 6 and LCM (6,10) = 30. For the least common multiple of more than 2 numbers, say a, b, c and d, it is the smallest integer that is evenly divisible by all numbers and can be calculated such that LCM (a,b,c,d) = LCM ( LCM ( LCM ( a,b ), c ), d ).
Which is the least common multiple for 6 and 8?
Supose you want to find the Least Common Multiple (LCM) for 6 and 8, notation LCM (6,8): The LCM of 6 and 8 is 24 because 24 is the smallest number that is both a multiple of 6 and a multiple of 8. This calculator uses the listing multiples method.
What are the common multiples of 3 and 4?
For example, to find the common multiples of 3 and 4, we list their multiples and then find their common multiples. Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, Common multiples of 3 and 4: 12, 24, 36, ….
Are there any nonzero numbers that have multiples?
All nonzero numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. 36 is a multiple of 4. 36 is a multiple of 9. 36 is a common multiple of 4 and 9. What are All common multiples for 4 and 9?
