Find LCM of 108,878,393,738,945 with Prime Factorization
2 | 108, 878, 393, 738, 945 |
3 | 54, 439, 393, 369, 945 |
3 | 18, 439, 131, 123, 315 |
3 | 6, 439, 131, 41, 105 |
2, 439, 131, 41, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 2 x 439 x 131 x 41 x 35 = 8912744820
Therefore, the lowest common multiple of 108,878,393,738,945 is 8912744820.
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.
108 x 878 x 393 x 738 x 945 = 25989563895120
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
878 : 1, 2, 439, 878
393 : 1, 3, 131, 393
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
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 108,878,393,738,945, is 1.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
878:2x 439
393:3x 131
738:2x 3x 3x 41
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.
2x 2x 3x 3x 3x 3x 3x 3 = 2916
Therefore, the value for common factors is 2916.
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 = 25989563895120/(1x2916)
LCM = 25989563895120/2916
LCM = 8912744820
Thus, we can understand that the LCM of 108,878,393,738,945 is 8912744820.
