Given numbers are 548,920,891,982,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 548,920,891,982,391 is 937381789080.
Find LCM of 548,920,891,982,391 with Prime Factorization
| 2 | 548, 920, 891, 982, 391 |
| 2 | 274, 460, 891, 491, 391 |
| 23 | 137, 230, 891, 491, 391 |
| 137, 10, 891, 491, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 137 x 10 x 891 x 491 x 17 = 937381789080
Therefore, the lowest common multiple of 548,920,891,982,391 is 937381789080.
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.
548 x 920 x 891 x 982 x 391 = 172478249190720
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.
548 : 1, 2, 4, 137, 274, 548
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
982 : 1, 2, 491, 982
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,920,891,982,391, is 1.
Now, the common factors can be found like this.
548:2x 2x 137
920:2x 2x 2x 5x 23
891:3x 3x 3x 3x 11
982:2x 491
391:17x 23
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 23 = 184
Therefore, the value for common factors is 184.
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 = 172478249190720/(1x184)
LCM = 172478249190720/184
LCM = 937381789080
Thus, we can understand that the LCM of 548,920,891,982,391 is 937381789080.
