Given numbers are 400,662,393,108
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,662,393,108 is 468298800.
Find LCM of 400,662,393,108 with Prime Factorization
| 2 | 400, 662, 393, 108 |
| 2 | 200, 331, 393, 54 |
| 3 | 100, 331, 393, 27 |
| 100, 331, 131, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 100 x 331 x 131 x 9 = 468298800
Therefore, the lowest common multiple of 400,662,393,108 is 468298800.
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.
400 x 662 x 393 x 108 = 11239171200
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
662 : 1, 2, 331, 662
393 : 1, 3, 131, 393
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,662,393,108, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
662:2x 331
393:3x 131
108:2x 2x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 11239171200/(1x24)
LCM = 11239171200/24
LCM = 468298800
Thus, we can understand that the LCM of 400,662,393,108 is 468298800.
