Find LCM of 343,690,848,928,975 with Prime Factorization
| 2 | 343, 690, 848, 928, 975 |
| 2 | 343, 345, 424, 464, 975 |
| 2 | 343, 345, 212, 232, 975 |
| 2 | 343, 345, 106, 116, 975 |

| 5 | 343, 115, 53, 58, 325 |
| 343, 23, 53, 58, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 343 x 23 x 53 x 58 x 65 = 378312261600
Therefore, the lowest common multiple of 343,690,848,928,975 is 378312261600.
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.
343 x 690 x 848 x 928 x 975 = 181589885568000
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.
343 : 1, 7, 49, 343
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,690,848,928,975, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
690:2x 3x 5x 23
848:2x 2x 2x 2x 53
928:2x 2x 2x 2x 2x 29
975:3x 5x 5x 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 2x 2x 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 181589885568000/(1x480)
LCM = 181589885568000/480
LCM = 378312261600
Thus, we can understand that the LCM of 343,690,848,928,975 is 378312261600.
