Given numbers are 704,286,578,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 704,286,578,847 is 203659456.
Find LCM of 704,286,578,847 with Prime Factorization
| 2 | 704, 286, 578, 847 |
| 11 | 352, 143, 289, 847 |
| 32, 13, 289, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 32 x 13 x 289 x 77 = 203659456
Therefore, the lowest common multiple of 704,286,578,847 is 203659456.
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.
704 x 286 x 578 x 847 = 98571176704
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
286 : 1, 2, 11, 13, 22, 26, 143, 286
578 : 1, 2, 17, 34, 289, 578
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,286,578,847, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
286:2x 11x 13
578:2x 17x 17
847:7x 11x 11
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 98571176704/(1x484)
LCM = 98571176704/484
LCM = 203659456
Thus, we can understand that the LCM of 704,286,578,847 is 203659456.
