The LCM of 828,581,392,289 is 1946401128.
Find LCM of 828,581,392,289 with Prime Factorization
| 2 | 828, 581, 392, 289 |
| 2 | 414, 581, 196, 289 |
| 7 | 207, 581, 98, 289 |
| 207, 83, 14, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 207 x 83 x 14 x 289 = 1946401128
Therefore, the lowest common multiple of 828,581,392,289 is 1946401128.
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.
828 x 581 x 392 x 289 = 54499231584
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
581 : 1, 7, 83, 581
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,581,392,289, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
581:7x 83
392:2x 2x 2x 7x 7
289:17x 17
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 7 = 28
Therefore, the value for common factors is 28.
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 = 54499231584/(1x28)
LCM = 54499231584/28
LCM = 1946401128
Thus, we can understand that the LCM of 828,581,392,289 is 1946401128.
