Given numbers are 113,788,490,815,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 113,788,490,815,904 is 7111944280.
Find LCM of 113,788,490,815,904 with Prime Factorization
| 2 | 113, 788, 490, 815, 904 |
| 2 | 113, 394, 245, 815, 452 |
| 5 | 113, 197, 245, 815, 226 |
| 113 | 113, 197, 49, 163, 226 |
| 1, 197, 49, 163, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 113 x 1 x 197 x 49 x 163 x 2 = 7111944280
Therefore, the lowest common multiple of 113,788,490,815,904 is 7111944280.
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.
113 x 788 x 490 x 815 x 904 = 32145988145600
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.
113 : 1, 113
788 : 1, 2, 4, 197, 394, 788
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
815 : 1, 5, 163, 815
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 113,788,490,815,904, is 1.
Now, the common factors can be found like this.
113:113
788:2x 2x 197
490:2x 5x 7x 7
815:5x 163
904:2x 2x 2x 113
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 5x 113 = 4520
Therefore, the value for common factors is 4520.
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 = 32145988145600/(1x4520)
LCM = 32145988145600/4520
LCM = 7111944280
Thus, we can understand that the LCM of 113,788,490,815,904 is 7111944280.
