Find LCM of 309,770,391,663,104 with Prime Factorization
| 2 | 309, 770, 391, 663, 104 |
| 3 | 309, 385, 391, 663, 52 |
| 13 | 103, 385, 391, 221, 52 |
| 17 | 103, 385, 391, 17, 4 |
| 103, 385, 23, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 103 x 385 x 23 x 1 x 4 = 4837592760
Therefore, the lowest common multiple of 309,770,391,663,104 is 4837592760.
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.
309 x 770 x 391 x 663 x 104 = 6414647999760
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.
309 : 1, 3, 103, 309
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
391 : 1, 17, 23, 391
663 : 1, 3, 13, 17, 39, 51, 221, 663
104 : 1, 2, 4, 8, 13, 26, 52, 104
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,770,391,663,104, is 1.
Now, the common factors can be found like this.
309:3x 103
770:2x 5x 7x 11
391:17x 23
663:3x 13x 17
104:2x 2x 2x 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 3x 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 6414647999760/(1x1326)
LCM = 6414647999760/1326
LCM = 4837592760
Thus, we can understand that the LCM of 309,770,391,663,104 is 4837592760.
