Find LCM of 820,858,442,210,626 with Prime Factorization
| 2 | 820, 858, 442, 210, 626 |
| 3 | 410, 429, 221, 105, 313 |
| 5 | 410, 143, 221, 35, 313 |
| 13 | 82, 143, 221, 7, 313 |
| 82, 11, 17, 7, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 82 x 11 x 17 x 7 x 313 = 13102749660
Therefore, the lowest common multiple of 820,858,442,210,626 is 13102749660.
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 858 x 442 x 210 x 626 = 40880578939200
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
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
442 : 1, 2, 13, 17, 26, 34, 221, 442
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
626 : 1, 2, 313, 626
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,858,442,210,626, is 2.
Now, the common factors can be found like this.
820:2x 2x 5x 41
858:2x 3x 11x 13
442:2x 13x 17
210:2x 3x 5x 7
626:2x 313
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 3x 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 40880578939200/(2x1560)
LCM = 40880578939200/3120
LCM = 13102749660
Thus, we can understand that the LCM of 820,858,442,210,626 is 13102749660.
