The LCM of 372,638,783,605 is 58740660.
Find LCM of 372,638,783,605 with Prime Factorization
| 2 | 372, 638, 783, 605 |
| 3 | 186, 319, 783, 605 |
| 11 | 62, 319, 261, 605 |
| 29 | 62, 29, 261, 55 |
| 62, 1, 9, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 62 x 1 x 9 x 55 = 58740660
Therefore, the lowest common multiple of 372,638,783,605 is 58740660.
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.
372 x 638 x 783 x 605 = 112429623240
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
638 : 1, 2, 11, 22, 29, 58, 319, 638
783 : 1, 3, 9, 27, 29, 87, 261, 783
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,638,783,605, is 1.
Now, the common factors can be found like this.
372:2x 2x 3x 31
638:2x 11x 29
783:3x 3x 3x 29
605:5x 11x 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 3x 11x 29 = 1914
Therefore, the value for common factors is 1914.
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 = 112429623240/(1x1914)
LCM = 112429623240/1914
LCM = 58740660
Thus, we can understand that the LCM of 372,638,783,605 is 58740660.
