Find LCM of 811,780,516,231,565 with Prime Factorization
| 2 | 811, 780, 516, 231, 565 |
| 2 | 811, 390, 258, 231, 565 |
| 3 | 811, 195, 129, 231, 565 |
| 5 | 811, 65, 43, 77, 565 |
| 811, 13, 43, 77, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 811 x 13 x 43 x 77 x 113 = 236675378940
Therefore, the lowest common multiple of 811,780,516,231,565 is 236675378940.
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.
811 x 780 x 516 x 231 x 565 = 42601568209200
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.
811 : 1, 811
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
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
231 : 1, 3, 7, 11, 21, 33, 77, 231
565 : 1, 5, 113, 565
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,780,516,231,565, is 1.
Now, the common factors can be found like this.
811:811
780:2x 2x 3x 5x 13
516:2x 2x 3x 43
231:3x 7x 11
565:5x 113
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 5 = 180
Therefore, the value for common factors is 180.
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 = 42601568209200/(1x180)
LCM = 42601568209200/180
LCM = 236675378940
Thus, we can understand that the LCM of 811,780,516,231,565 is 236675378940.
