Given numbers are 3993,8478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3993,8478 is 11284218.
Find LCM of 3993,8478 with Prime Factorization
| 3 | 3993, 8478 |
| 1331, 2826 |
Multiply the prime numbers at the bottom and the left side.
3 x 1331 x 2826 = 11284218
Therefore, the lowest common multiple of 3993,8478 is 11284218.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
3993 x 8478 = 33852654
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
3993 : 1, 3, 11, 33, 121, 363, 1331, 3993
8478 : 1, 2, 3, 6, 9, 18, 27, 54, 157, 314, 471, 942, 1413, 2826, 4239, 8478
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3993,8478, is 3.
Now, the common factors can be found like this.
3993:3x 11x 11x 11
8478:2x 3x 3x 3x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 33852654/(3x1)
LCM = 33852654/3
LCM = 11284218
Thus, we can understand that the LCM of 3993,8478 is 11284218.
