Find LCM of 969,192,861,943,399 with Prime Factorization
| 3 | 969, 192, 861, 943, 399 |
| 7 | 323, 64, 287, 943, 133 |
| 19 | 323, 64, 41, 943, 19 |
| 41 | 17, 64, 41, 943, 1 |
| 17, 64, 1, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 41 x 17 x 64 x 1 x 23 x 1 = 409367616
Therefore, the lowest common multiple of 969,192,861,943,399 is 409367616.
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.
969 x 192 x 861 x 943 x 399 = 60271603471296
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
861 : 1, 3, 7, 21, 41, 123, 287, 861
943 : 1, 23, 41, 943
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,192,861,943,399, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
192:2x 2x 2x 2x 2x 2x 3
861:3x 7x 41
943:23x 41
399:3x 7x 19
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 7x 19x 41 = 147231
Therefore, the value for common factors is 147231.
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 = 60271603471296/(1x147231)
LCM = 60271603471296/147231
LCM = 409367616
Thus, we can understand that the LCM of 969,192,861,943,399 is 409367616.
