Find LCM of 829,642,192,856 with Prime Factorization
| 2 | 829, 642, 192, 856 |
| 2 | 829, 321, 96, 428 |
| 2 | 829, 321, 48, 214 |
| 3 | 829, 321, 24, 107 |
| 107 | 829, 107, 8, 107 |
| 829, 1, 8, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 107 x 829 x 1 x 8 x 1 = 17030976
Therefore, the lowest common multiple of 829,642,192,856 is 17030976.
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.
829 x 642 x 192 x 856 = 87471092736
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.
829 : 1, 829
642 : 1, 2, 3, 6, 107, 214, 321, 642
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,642,192,856, is 1.
Now, the common factors can be found like this.
829:829
642:2x 3x 107
192:2x 2x 2x 2x 2x 2x 3
856:2x 2x 2x 107
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 3x 107 = 5136
Therefore, the value for common factors is 5136.
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 = 87471092736/(1x5136)
LCM = 87471092736/5136
LCM = 17030976
Thus, we can understand that the LCM of 829,642,192,856 is 17030976.
