Given numbers are 381,231,658,246
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,231,658,246 is 113064798.
Find LCM of 381,231,658,246 with Prime Factorization
| 2 | 381, 231, 658, 246 |
| 3 | 381, 231, 329, 123 |
| 7 | 127, 77, 329, 41 |
| 127, 11, 47, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 127 x 11 x 47 x 41 = 113064798
Therefore, the lowest common multiple of 381,231,658,246 is 113064798.
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.
381 x 231 x 658 x 246 = 14246164548
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.
381 : 1, 3, 127, 381
231 : 1, 3, 7, 11, 21, 33, 77, 231
658 : 1, 2, 7, 14, 47, 94, 329, 658
246 : 1, 2, 3, 6, 41, 82, 123, 246
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,231,658,246, is 1.
Now, the common factors can be found like this.
381:3x 127
231:3x 7x 11
658:2x 7x 47
246:2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 14246164548/(1x126)
LCM = 14246164548/126
LCM = 113064798
Thus, we can understand that the LCM of 381,231,658,246 is 113064798.
