Find LCM of 838,612,964,384,765 with Prime Factorization
| 2 | 838, 612, 964, 384, 765 |
| 2 | 419, 306, 482, 192, 765 |
| 3 | 419, 153, 241, 96, 765 |
| 3 | 419, 51, 241, 32, 255 |
| 17 | 419, 17, 241, 32, 85 |
| 419, 1, 241, 32, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 419 x 1 x 241 x 32 x 5 = 9887863680
Therefore, the lowest common multiple of 838,612,964,384,765 is 9887863680.
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.
838 x 612 x 964 x 384 x 765 = 145232941731840
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.
838 : 1, 2, 419, 838
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
964 : 1, 2, 4, 241, 482, 964
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,612,964,384,765, is 1.
Now, the common factors can be found like this.
838:2x 419
612:2x 2x 3x 3x 17
964:2x 2x 241
384:2x 2x 2x 2x 2x 2x 2x 3
765:3x 3x 5x 17
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 2x 2x 2x 3x 3x 3x 17 = 14688
Therefore, the value for common factors is 14688.
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 = 145232941731840/(1x14688)
LCM = 145232941731840/14688
LCM = 9887863680
Thus, we can understand that the LCM of 838,612,964,384,765 is 9887863680.
