The LCM of 813,576,342,758 is 1124047296.
Find LCM of 813,576,342,758 with Prime Factorization
| 2 | 813, 576, 342, 758 |
| 3 | 813, 288, 171, 379 |
| 3 | 271, 96, 57, 379 |
| 271, 32, 19, 379 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 271 x 32 x 19 x 379 = 1124047296
Therefore, the lowest common multiple of 813,576,342,758 is 1124047296.
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 576 x 342 x 758 = 121397107968
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
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
758 : 1, 2, 379, 758
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,576,342,758, is 1.
Now, the common factors can be found like this.
813:3x 271
576:2x 2x 2x 2x 2x 2x 3x 3
342:2x 3x 3x 19
758:2x 379
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 121397107968/(1x108)
LCM = 121397107968/108
LCM = 1124047296
Thus, we can understand that the LCM of 813,576,342,758 is 1124047296.
