Find LCM of 819,893,108,945 with Prime Factorization
| 3 | 819, 893, 108, 945 |
| 3 | 273, 893, 36, 315 |
| 3 | 91, 893, 12, 105 |
| 7 | 91, 893, 4, 35 |
| 13, 893, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 13 x 893 x 4 x 5 = 43882020
Therefore, the lowest common multiple of 819,893,108,945 is 43882020.
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 893 x 108 x 945 = 74643316020
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
893 : 1, 19, 47, 893
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,893,108,945, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
893:19x 47
108:2x 2x 3x 3x 3
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 7 = 1701
Therefore, the value for common factors is 1701.
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 = 74643316020/(1x1701)
LCM = 74643316020/1701
LCM = 43882020
Thus, we can understand that the LCM of 819,893,108,945 is 43882020.
