Find LCM of 928,825,870,385 with Prime Factorization
| 2 | 928, 825, 870, 385 |
| 3 | 464, 825, 435, 385 |
| 5 | 464, 275, 145, 385 |
| 11 | 464, 55, 29, 77 |
| 29 | 464, 5, 29, 7 |
| 16, 5, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 29 x 16 x 5 x 1 x 7 = 5359200
Therefore, the lowest common multiple of 928,825,870,385 is 5359200.
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.
928 x 825 x 870 x 385 = 256437720000
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,825,870,385, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
825:3x 5x 5x 11
870:2x 3x 5x 29
385:5x 7x 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 3x 5x 5x 11x 29 = 47850
Therefore, the value for common factors is 47850.
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 = 256437720000/(1x47850)
LCM = 256437720000/47850
LCM = 5359200
Thus, we can understand that the LCM of 928,825,870,385 is 5359200.
