Given numbers are 798,857,828,760
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 798,857,828,760 is 943762680.
Find LCM of 798,857,828,760 with Prime Factorization
| 2 | 798, 857, 828, 760 |
| 2 | 399, 857, 414, 380 |
| 3 | 399, 857, 207, 190 |
| 19 | 133, 857, 69, 190 |
| 7, 857, 69, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 7 x 857 x 69 x 10 = 943762680
Therefore, the lowest common multiple of 798,857,828,760 is 943762680.
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.
798 x 857 x 828 x 760 = 430355782080
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
857 : 1, 857
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,857,828,760, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
857:857
828:2x 2x 3x 3x 23
760:2x 2x 2x 5x 19
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 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 430355782080/(1x456)
LCM = 430355782080/456
LCM = 943762680
Thus, we can understand that the LCM of 798,857,828,760 is 943762680.
