Given numbers are 845,814,825,415
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,814,825,415 is 856348350.
Find LCM of 845,814,825,415 with Prime Factorization
| 5 | 845, 814, 825, 415 |
| 11 | 169, 814, 165, 83 |
| 169, 74, 15, 83 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 169 x 74 x 15 x 83 = 856348350
Therefore, the lowest common multiple of 845,814,825,415 is 856348350.
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.
845 x 814 x 825 x 415 = 235495796250
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.
845 : 1, 5, 13, 65, 169, 845
814 : 1, 2, 11, 22, 37, 74, 407, 814
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,814,825,415, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
814:2x 11x 37
825:3x 5x 5x 11
415:5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 11 = 275
Therefore, the value for common factors is 275.
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 = 235495796250/(1x275)
LCM = 235495796250/275
LCM = 856348350
Thus, we can understand that the LCM of 845,814,825,415 is 856348350.
