The LCM of 512,780,408,406,628 is 54094010880.
Find LCM of 512,780,408,406,628 with Prime Factorization
| 2 | 512, 780, 408, 406, 628 |
| 2 | 256, 390, 204, 203, 314 |
| 2 | 128, 195, 102, 203, 157 |
| 3 | 64, 195, 51, 203, 157 |
| 64, 65, 17, 203, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 64 x 65 x 17 x 203 x 157 = 54094010880
Therefore, the lowest common multiple of 512,780,408,406,628 is 54094010880.
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.
512 x 780 x 408 x 406 x 628 = 41544200355840
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
406 : 1, 2, 7, 14, 29, 58, 203, 406
628 : 1, 2, 4, 157, 314, 628
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,780,408,406,628, is 2.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
780:2x 2x 3x 5x 13
408:2x 2x 2x 3x 17
406:2x 7x 29
628:2x 2x 157
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 2x 3 = 384
Therefore, the value for common factors is 384.
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 = 41544200355840/(2x384)
LCM = 41544200355840/768
LCM = 54094010880
Thus, we can understand that the LCM of 512,780,408,406,628 is 54094010880.
