Given numbers are 806,546,900,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,546,900,785 is 398607300.
Find LCM of 806,546,900,785 with Prime Factorization
| 2 | 806, 546, 900, 785 |
| 3 | 403, 273, 450, 785 |
| 5 | 403, 91, 150, 785 |
| 13 | 403, 91, 30, 157 |
| 31, 7, 30, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 31 x 7 x 30 x 157 = 398607300
Therefore, the lowest common multiple of 806,546,900,785 is 398607300.
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.
806 x 546 x 900 x 785 = 310913694000
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,546,900,785, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
546:2x 3x 7x 13
900:2x 2x 3x 3x 5x 5
785:5x 157
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 3x 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 310913694000/(1x780)
LCM = 310913694000/780
LCM = 398607300
Thus, we can understand that the LCM of 806,546,900,785 is 398607300.
