Given numbers are 578,398,981,780,907
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,398,981,780,907 is 13304561383620.
Find LCM of 578,398,981,780,907 with Prime Factorization
| 2 | 578, 398, 981, 780, 907 |
| 3 | 289, 199, 981, 390, 907 |
| 289, 199, 327, 130, 907 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 289 x 199 x 327 x 130 x 907 = 13304561383620
Therefore, the lowest common multiple of 578,398,981,780,907 is 13304561383620.
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.
578 x 398 x 981 x 780 x 907 = 159654736603440
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.
578 : 1, 2, 17, 34, 289, 578
398 : 1, 2, 199, 398
981 : 1, 3, 9, 109, 327, 981
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
907 : 1, 907
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,398,981,780,907, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
398:2x 199
981:3x 3x 109
780:2x 2x 3x 5x 13
907:907
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 3 = 12
Therefore, the value for common factors is 12.
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 = 159654736603440/(1x12)
LCM = 159654736603440/12
LCM = 13304561383620
Thus, we can understand that the LCM of 578,398,981,780,907 is 13304561383620.
