Given numbers are 382,379,438,821,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,379,438,821,803 is 286340335842.
Find LCM of 382,379,438,821,803 with Prime Factorization
| 2 | 382, 379, 438, 821, 803 |
| 73 | 191, 379, 219, 821, 803 |
| 191, 379, 3, 821, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 73 x 191 x 379 x 3 x 821 x 11 = 286340335842
Therefore, the lowest common multiple of 382,379,438,821,803 is 286340335842.
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.
382 x 379 x 438 x 821 x 803 = 41805689032932
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.
382 : 1, 2, 191, 382
379 : 1, 379
438 : 1, 2, 3, 6, 73, 146, 219, 438
821 : 1, 821
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,379,438,821,803, is 1.
Now, the common factors can be found like this.
382:2x 191
379:379
438:2x 3x 73
821:821
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 73 = 146
Therefore, the value for common factors is 146.
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 = 41805689032932/(1x146)
LCM = 41805689032932/146
LCM = 286340335842
Thus, we can understand that the LCM of 382,379,438,821,803 is 286340335842.
