Given numbers are 383,680,856,663,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 383,680,856,663,428 is 1086816120.
Find LCM of 383,680,856,663,428 with Prime Factorization
| 2 | 383, 680, 856, 663, 428 |
| 2 | 383, 340, 428, 663, 214 |
| 2 | 383, 170, 107, 663, 214 |
| 17 | 383, 85, 107, 663, 107 |
| 107 | 383, 5, 107, 39, 107 |
| 383, 5, 1, 39, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 107 x 383 x 5 x 1 x 39 x 1 = 1086816120
Therefore, the lowest common multiple of 383,680,856,663,428 is 1086816120.
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.
383 x 680 x 856 x 663 x 428 = 63261392712960
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.
383 : 1, 383
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
856 : 1, 2, 4, 8, 107, 214, 428, 856
663 : 1, 3, 13, 17, 39, 51, 221, 663
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 383,680,856,663,428, is 1.
Now, the common factors can be found like this.
383:383
680:2x 2x 2x 5x 17
856:2x 2x 2x 107
663:3x 13x 17
428:2x 2x 107
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 2x 2x 17x 107 = 58208
Therefore, the value for common factors is 58208.
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 = 63261392712960/(1x58208)
LCM = 63261392712960/58208
LCM = 1086816120
Thus, we can understand that the LCM of 383,680,856,663,428 is 1086816120.
