Find LCM of 855,865,788,684,176 with Prime Factorization
| 2 | 855, 865, 788, 684, 176 |
| 2 | 855, 865, 394, 342, 88 |
| 3 | 855, 865, 197, 171, 44 |
| 3 | 285, 865, 197, 57, 44 |
| 5 | 95, 865, 197, 19, 44 |
| 19 | 19, 173, 197, 19, 44 |
| 1, 173, 197, 1, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 1 x 173 x 197 x 1 x 44 = 5128508880
Therefore, the lowest common multiple of 855,865,788,684,176 is 5128508880.
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.
855 x 865 x 788 x 684 x 176 = 70158001478400
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
865 : 1, 5, 173, 865
788 : 1, 2, 4, 197, 394, 788
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,865,788,684,176, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
865:5x 173
788:2x 2x 197
684:2x 2x 3x 3x 19
176:2x 2x 2x 2x 11
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 5x 19 = 13680
Therefore, the value for common factors is 13680.
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 = 70158001478400/(1x13680)
LCM = 70158001478400/13680
LCM = 5128508880
Thus, we can understand that the LCM of 855,865,788,684,176 is 5128508880.
