Find LCM of 786,694,297,945,865 with Prime Factorization
| 2 | 786, 694, 297, 945, 865 |
| 3 | 393, 347, 297, 945, 865 |
| 3 | 131, 347, 99, 315, 865 |
| 3 | 131, 347, 33, 105, 865 |
| 5 | 131, 347, 11, 35, 865 |
| 131, 347, 11, 7, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 131 x 347 x 11 x 7 x 173 = 163493828190
Therefore, the lowest common multiple of 786,694,297,945,865 is 163493828190.
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.
786 x 694 x 297 x 945 x 865 = 132430000833900
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
694 : 1, 2, 347, 694
297 : 1, 3, 9, 11, 27, 33, 99, 297
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,694,297,945,865, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
694:2x 347
297:3x 3x 3x 11
945:3x 3x 3x 5x 7
865:5x 173
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 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 132430000833900/(1x810)
LCM = 132430000833900/810
LCM = 163493828190
Thus, we can understand that the LCM of 786,694,297,945,865 is 163493828190.
