The LCM of 845,861,838,406,702 is 159127187310.
Find LCM of 845,861,838,406,702 with Prime Factorization
| 2 | 845, 861, 838, 406, 702 |
| 3 | 845, 861, 419, 203, 351 |
| 7 | 845, 287, 419, 203, 117 |
| 13 | 845, 41, 419, 29, 117 |
| 65, 41, 419, 29, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 65 x 41 x 419 x 29 x 9 = 159127187310
Therefore, the lowest common multiple of 845,861,838,406,702 is 159127187310.
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.
845 x 861 x 838 x 406 x 702 = 173766888542520
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.
845 : 1, 5, 13, 65, 169, 845
861 : 1, 3, 7, 21, 41, 123, 287, 861
838 : 1, 2, 419, 838
406 : 1, 2, 7, 14, 29, 58, 203, 406
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,861,838,406,702, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
861:3x 7x 41
838:2x 419
406:2x 7x 29
702:2x 3x 3x 3x 13
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 7x 13 = 1092
Therefore, the value for common factors is 1092.
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 = 173766888542520/(1x1092)
LCM = 173766888542520/1092
LCM = 159127187310
Thus, we can understand that the LCM of 845,861,838,406,702 is 159127187310.
