Find LCM of 834,678,828,849,644 with Prime Factorization
| 2 | 834, 678, 828, 849, 644 |
| 2 | 417, 339, 414, 849, 322 |
| 3 | 417, 339, 207, 849, 161 |
| 23 | 139, 113, 69, 283, 161 |
| 139, 113, 3, 283, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 139 x 113 x 3 x 283 x 7 = 25763689476
Therefore, the lowest common multiple of 834,678,828,849,644 is 25763689476.
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.
834 x 678 x 828 x 849 x 644 = 255988018633536
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
678 : 1, 2, 3, 6, 113, 226, 339, 678
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
849 : 1, 3, 283, 849
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,678,828,849,644, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
678:2x 3x 113
828:2x 2x 3x 3x 23
849:3x 283
644:2x 2x 7x 23
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 3x 3x 23 = 9936
Therefore, the value for common factors is 9936.
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 = 255988018633536/(1x9936)
LCM = 255988018633536/9936
LCM = 25763689476
Thus, we can understand that the LCM of 834,678,828,849,644 is 25763689476.
