The LCM of 820,902,856,539 is 94583720.
Find LCM of 820,902,856,539 with Prime Factorization
| 2 | 820, 902, 856, 539 |
| 2 | 410, 451, 428, 539 |
| 11 | 205, 451, 214, 539 |
| 41 | 205, 41, 214, 49 |
| 5, 1, 214, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 41 x 5 x 1 x 214 x 49 = 94583720
Therefore, the lowest common multiple of 820,902,856,539 is 94583720.
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.
820 x 902 x 856 x 539 = 341258061760
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
902 : 1, 2, 11, 22, 41, 82, 451, 902
856 : 1, 2, 4, 8, 107, 214, 428, 856
539 : 1, 7, 11, 49, 77, 539
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,902,856,539, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
902:2x 11x 41
856:2x 2x 2x 107
539:7x 7x 11
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 11x 41 = 3608
Therefore, the value for common factors is 3608.
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 = 341258061760/(1x3608)
LCM = 341258061760/3608
LCM = 94583720
Thus, we can understand that the LCM of 820,902,856,539 is 94583720.
