Find LCM of 861,917,867,402,204 with Prime Factorization
| 2 | 861, 917, 867, 402, 204 |
| 3 | 861, 917, 867, 201, 102 |
| 7 | 287, 917, 289, 67, 34 |
| 17 | 41, 131, 289, 67, 34 |
| 41, 131, 17, 67, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 41 x 131 x 17 x 67 x 2 = 8735888532
Therefore, the lowest common multiple of 861,917,867,402,204 is 8735888532.
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 917 x 867 x 402 x 204 = 56136819706632
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
917 : 1, 7, 131, 917
867 : 1, 3, 17, 51, 289, 867
402 : 1, 2, 3, 6, 67, 134, 201, 402
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,917,867,402,204, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
917:7x 131
867:3x 17x 17
402:2x 3x 67
204:2x 2x 3x 17
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 3x 3x 7x 17 = 6426
Therefore, the value for common factors is 6426.
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 = 56136819706632/(1x6426)
LCM = 56136819706632/6426
LCM = 8735888532
Thus, we can understand that the LCM of 861,917,867,402,204 is 8735888532.
