Find LCM of 856,560,138,889,450 with Prime Factorization
| 2 | 856, 560, 138, 889, 450 |
| 2 | 428, 280, 69, 889, 225 |
| 2 | 214, 140, 69, 889, 225 |
| 3 | 107, 70, 69, 889, 225 |
| 5 | 107, 70, 23, 889, 75 |
| 7 | 107, 14, 23, 889, 15 |
| 107, 2, 23, 127, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 107 x 2 x 23 x 127 x 15 = 7876184400
Therefore, the lowest common multiple of 856,560,138,889,450 is 7876184400.
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.
856 x 560 x 138 x 889 x 450 = 26463979584000
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
138 : 1, 2, 3, 6, 23, 46, 69, 138
889 : 1, 7, 127, 889
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,560,138,889,450, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
560:2x 2x 2x 2x 5x 7
138:2x 3x 23
889:7x 127
450:2x 3x 3x 5x 5
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 2x 2x 3x 5x 7 = 3360
Therefore, the value for common factors is 3360.
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 = 26463979584000/(1x3360)
LCM = 26463979584000/3360
LCM = 7876184400
Thus, we can understand that the LCM of 856,560,138,889,450 is 7876184400.
