Given numbers are 845,490,685,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,490,685,286 is 124794670.
Find LCM of 845,490,685,286 with Prime Factorization
| 2 | 845, 490, 685, 286 |
| 5 | 845, 245, 685, 143 |
| 13 | 169, 49, 137, 143 |
| 13, 49, 137, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 13 x 49 x 137 x 11 = 124794670
Therefore, the lowest common multiple of 845,490,685,286 is 124794670.
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 490 x 685 x 286 = 81116535500
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
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
685 : 1, 5, 137, 685
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,490,685,286, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
490:2x 5x 7x 7
685:5x 137
286:2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 13 = 650
Therefore, the value for common factors is 650.
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 = 81116535500/(1x650)
LCM = 81116535500/650
LCM = 124794670
Thus, we can understand that the LCM of 845,490,685,286 is 124794670.
