Find LCM of 378,945,775,634 with Prime Factorization
| 2 | 378, 945, 775, 634 |
| 3 | 189, 945, 775, 317 |
| 3 | 63, 315, 775, 317 |
| 3 | 21, 105, 775, 317 |
| 5 | 7, 35, 775, 317 |
| 7 | 7, 7, 155, 317 |
| 1, 1, 155, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 7 x 1 x 1 x 155 x 317 = 92865150
Therefore, the lowest common multiple of 378,945,775,634 is 92865150.
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.
378 x 945 x 775 x 634 = 175515133500
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
775 : 1, 5, 25, 31, 155, 775
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,945,775,634, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
945:3x 3x 3x 5x 7
775:5x 5x 31
634:2x 317
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 5x 7 = 1890
Therefore, the value for common factors is 1890.
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 = 175515133500/(1x1890)
LCM = 175515133500/1890
LCM = 92865150
Thus, we can understand that the LCM of 378,945,775,634 is 92865150.
