Find LCM of 343,920,872,735 with Prime Factorization
| 2 | 343, 920, 872, 735 |
| 2 | 343, 460, 436, 735 |
| 2 | 343, 230, 218, 735 |
| 5 | 343, 115, 109, 735 |
| 7 | 343, 23, 109, 147 |
| 7 | 49, 23, 109, 21 |
| 7, 23, 109, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 7 x 7 x 23 x 109 x 3 = 103188120
Therefore, the lowest common multiple of 343,920,872,735 is 103188120.
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 920 x 872 x 735 = 202248715200
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
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
872 : 1, 2, 4, 8, 109, 218, 436, 872
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,920,872,735, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
920:2x 2x 2x 5x 23
872:2x 2x 2x 109
735:3x 5x 7x 7
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 5x 7x 7 = 1960
Therefore, the value for common factors is 1960.
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 = 202248715200/(1x1960)
LCM = 202248715200/1960
LCM = 103188120
Thus, we can understand that the LCM of 343,920,872,735 is 103188120.
