Find LCM of 758,380,629,969,861 with Prime Factorization
| 2 | 758, 380, 629, 969, 861 |
| 3 | 379, 190, 629, 969, 861 |
| 17 | 379, 190, 629, 323, 287 |
| 19 | 379, 190, 37, 19, 287 |
| 379, 10, 37, 1, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 379 x 10 x 37 x 1 x 287 = 77996767380
Therefore, the lowest common multiple of 758,380,629,969,861 is 77996767380.
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 380 x 629 x 969 x 861 = 151157735182440
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
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
629 : 1, 17, 37, 629
969 : 1, 3, 17, 19, 51, 57, 323, 969
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,380,629,969,861, is 1.
Now, the common factors can be found like this.
758:2x 379
380:2x 2x 5x 19
629:17x 37
969:3x 17x 19
861:3x 7x 41
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 17x 19 = 1938
Therefore, the value for common factors is 1938.
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 = 151157735182440/(1x1938)
LCM = 151157735182440/1938
LCM = 77996767380
Thus, we can understand that the LCM of 758,380,629,969,861 is 77996767380.
