The LCM of 705,176,912,786 is 308835120.
Find LCM of 705,176,912,786 with Prime Factorization
| 2 | 705, 176, 912, 786 |
| 2 | 705, 88, 456, 393 |
| 2 | 705, 44, 228, 393 |
| 2 | 705, 22, 114, 393 |
| 3 | 705, 11, 57, 393 |
| 235, 11, 19, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 235 x 11 x 19 x 131 = 308835120
Therefore, the lowest common multiple of 705,176,912,786 is 308835120.
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.
705 x 176 x 912 x 786 = 88944514560
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,176,912,786, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
176:2x 2x 2x 2x 11
912:2x 2x 2x 2x 3x 19
786:2x 3x 131
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 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 88944514560/(1x288)
LCM = 88944514560/288
LCM = 308835120
Thus, we can understand that the LCM of 705,176,912,786 is 308835120.
