Given numbers are 381,476,157,260,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,476,157,260,828 is 127700920620.
Find LCM of 381,476,157,260,828 with Prime Factorization
| 2 | 381, 476, 157, 260, 828 |
| 2 | 381, 238, 157, 130, 414 |
| 3 | 381, 119, 157, 65, 207 |
| 127, 119, 157, 65, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 127 x 119 x 157 x 65 x 69 = 127700920620
Therefore, the lowest common multiple of 381,476,157,260,828 is 127700920620.
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 476 x 157 x 260 x 828 = 6129644189760
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
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
157 : 1, 157
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,476,157,260,828, is 1.
Now, the common factors can be found like this.
381:3x 127
476:2x 2x 7x 17
157:157
260:2x 2x 5x 13
828:2x 2x 3x 3x 23
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 3 = 48
Therefore, the value for common factors is 48.
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 = 6129644189760/(1x48)
LCM = 6129644189760/48
LCM = 127700920620
Thus, we can understand that the LCM of 381,476,157,260,828 is 127700920620.
