Find LCM of 308,780,913,351 with Prime Factorization
| 2 | 308, 780, 913, 351 |
| 2 | 154, 390, 913, 351 |
| 3 | 77, 195, 913, 351 |
| 11 | 77, 65, 913, 117 |
| 13 | 7, 65, 83, 117 |
| 7, 5, 83, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 7 x 5 x 83 x 9 = 44864820
Therefore, the lowest common multiple of 308,780,913,351 is 44864820.
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.
308 x 780 x 913 x 351 = 76988031120
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
913 : 1, 11, 83, 913
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,780,913,351, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
780:2x 2x 3x 5x 13
913:11x 83
351:3x 3x 3x 13
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 11x 13 = 1716
Therefore, the value for common factors is 1716.
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 = 76988031120/(1x1716)
LCM = 76988031120/1716
LCM = 44864820
Thus, we can understand that the LCM of 308,780,913,351 is 44864820.
