Given numbers are 807,720,857,792
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,720,857,792 is 1825821360.
Find LCM of 807,720,857,792 with Prime Factorization
| 2 | 807, 720, 857, 792 |
| 2 | 807, 360, 857, 396 |
| 2 | 807, 180, 857, 198 |
| 3 | 807, 90, 857, 99 |
| 3 | 269, 30, 857, 33 |
| 269, 10, 857, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 269 x 10 x 857 x 11 = 1825821360
Therefore, the lowest common multiple of 807,720,857,792 is 1825821360.
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.
807 x 720 x 857 x 792 = 394377413760
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.
807 : 1, 3, 269, 807
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
857 : 1, 857
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,720,857,792, is 1.
Now, the common factors can be found like this.
807:3x 269
720:2x 2x 2x 2x 3x 3x 5
857:857
792:2x 2x 2x 3x 3x 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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 394377413760/(1x216)
LCM = 394377413760/216
LCM = 1825821360
Thus, we can understand that the LCM of 807,720,857,792 is 1825821360.
