The LCM of 813,440,968,582 is 381687240.
Find LCM of 813,440,968,582 with Prime Factorization
| 2 | 813, 440, 968, 582 |
| 2 | 813, 220, 484, 291 |
| 2 | 813, 110, 242, 291 |
| 3 | 813, 55, 121, 291 |
| 11 | 271, 55, 121, 97 |
| 271, 5, 11, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 271 x 5 x 11 x 97 = 381687240
Therefore, the lowest common multiple of 813,440,968,582 is 381687240.
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.
813 x 440 x 968 x 582 = 201530862720
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.
813 : 1, 3, 271, 813
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
582 : 1, 2, 3, 6, 97, 194, 291, 582
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,440,968,582, is 1.
Now, the common factors can be found like this.
813:3x 271
440:2x 2x 2x 5x 11
968:2x 2x 2x 11x 11
582:2x 3x 97
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 3x 11 = 528
Therefore, the value for common factors is 528.
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 = 201530862720/(1x528)
LCM = 201530862720/528
LCM = 381687240
Thus, we can understand that the LCM of 813,440,968,582 is 381687240.
