Find LCM of 819,616,609,638,878 with Prime Factorization
| 2 | 819, 616, 609, 638, 878 |
| 3 | 819, 308, 609, 319, 439 |
| 7 | 273, 308, 203, 319, 439 |
| 11 | 39, 44, 29, 319, 439 |
| 29 | 39, 4, 29, 29, 439 |
| 39, 4, 1, 1, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 29 x 39 x 4 x 1 x 1 x 439 = 917548632
Therefore, the lowest common multiple of 819,616,609,638,878 is 917548632.
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.
819 x 616 x 609 x 638 x 878 = 172106432001504
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
609 : 1, 3, 7, 21, 29, 87, 203, 609
638 : 1, 2, 11, 22, 29, 58, 319, 638
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,616,609,638,878, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
616:2x 2x 2x 7x 11
609:3x 7x 29
638:2x 11x 29
878:2x 439
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 7x 11x 29 = 187572
Therefore, the value for common factors is 187572.
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 = 172106432001504/(1x187572)
LCM = 172106432001504/187572
LCM = 917548632
Thus, we can understand that the LCM of 819,616,609,638,878 is 917548632.
