Given numbers are 516,768,392,328
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 516,768,392,328 is 66345216.
Find LCM of 516,768,392,328 with Prime Factorization
| 2 | 516, 768, 392, 328 |
| 2 | 258, 384, 196, 164 |
| 2 | 129, 192, 98, 82 |
| 3 | 129, 96, 49, 41 |
| 43, 32, 49, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 43 x 32 x 49 x 41 = 66345216
Therefore, the lowest common multiple of 516,768,392,328 is 66345216.
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.
516 x 768 x 392 x 328 = 50953125888
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
328 : 1, 2, 4, 8, 41, 82, 164, 328
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,768,392,328, is 4.
Now, the common factors can be found like this.
516:2x 2x 3x 43
768:2x 2x 2x 2x 2x 2x 2x 2x 3
392:2x 2x 2x 7x 7
328:2x 2x 2x 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 2x 2x 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 50953125888/(4x192)
LCM = 50953125888/768
LCM = 66345216
Thus, we can understand that the LCM of 516,768,392,328 is 66345216.
