The LCM of 758,871,810,378 is 1871718030.
Find LCM of 758,871,810,378 with Prime Factorization
| 2 | 758, 871, 810, 378 |
| 3 | 379, 871, 405, 189 |
| 3 | 379, 871, 135, 63 |
| 3 | 379, 871, 45, 21 |
| 379, 871, 15, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 379 x 871 x 15 x 7 = 1871718030
Therefore, the lowest common multiple of 758,871,810,378 is 1871718030.
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.
758 x 871 x 810 x 378 = 202145547240
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.
758 : 1, 2, 379, 758
871 : 1, 13, 67, 871
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,871,810,378, is 1.
Now, the common factors can be found like this.
758:2x 379
871:13x 67
810:2x 3x 3x 3x 3x 5
378:2x 3x 3x 3x 7
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 202145547240/(1x108)
LCM = 202145547240/108
LCM = 1871718030
Thus, we can understand that the LCM of 758,871,810,378 is 1871718030.
