Given numbers are 631,188,517,381,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,188,517,381,218 is 54191524332.
Find LCM of 631,188,517,381,218 with Prime Factorization
| 2 | 631, 188, 517, 381, 218 |
| 47 | 631, 94, 517, 381, 109 |
| 631, 2, 11, 381, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 47 x 631 x 2 x 11 x 381 x 109 = 54191524332
Therefore, the lowest common multiple of 631,188,517,381,218 is 54191524332.
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.
631 x 188 x 517 x 381 x 218 = 5094003287208
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.
631 : 1, 631
188 : 1, 2, 4, 47, 94, 188
517 : 1, 11, 47, 517
381 : 1, 3, 127, 381
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,188,517,381,218, is 1.
Now, the common factors can be found like this.
631:631
188:2x 2x 47
517:11x 47
381:3x 127
218:2x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 47 = 94
Therefore, the value for common factors is 94.
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 = 5094003287208/(1x94)
LCM = 5094003287208/94
LCM = 54191524332
Thus, we can understand that the LCM of 631,188,517,381,218 is 54191524332.
