Find LCM of 861,544,502,879,644 with Prime Factorization
| 2 | 861, 544, 502, 879, 644 |
| 2 | 861, 272, 251, 879, 322 |
| 3 | 861, 136, 251, 879, 161 |
| 7 | 287, 136, 251, 293, 161 |
| 41, 136, 251, 293, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 41 x 136 x 251 x 293 x 23 = 792266383776
Therefore, the lowest common multiple of 861,544,502,879,644 is 792266383776.
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.
861 x 544 x 502 x 879 x 644 = 133100752474368
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
502 : 1, 2, 251, 502
879 : 1, 3, 293, 879
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 861,544,502,879,644, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
544:2x 2x 2x 2x 2x 17
502:2x 251
879:3x 293
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 133100752474368/(1x168)
LCM = 133100752474368/168
LCM = 792266383776
Thus, we can understand that the LCM of 861,544,502,879,644 is 792266383776.
