Find LCM of 343,918,855,170,875 with Prime Factorization
| 2 | 343, 918, 855, 170, 875 |
| 3 | 343, 459, 855, 85, 875 |
| 3 | 343, 153, 285, 85, 875 |
| 5 | 343, 51, 95, 85, 875 |
| 7 | 343, 51, 19, 17, 175 |
| 17 | 49, 51, 19, 17, 25 |
| 49, 3, 19, 1, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 17 x 49 x 3 x 19 x 1 x 25 = 747825750
Therefore, the lowest common multiple of 343,918,855,170,875 is 747825750.
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 918 x 855 x 170 x 875 = 40046068912500
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
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
170 : 1, 2, 5, 10, 17, 34, 85, 170
875 : 1, 5, 7, 25, 35, 125, 175, 875
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,918,855,170,875, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
918:2x 3x 3x 3x 17
855:3x 3x 5x 19
170:2x 5x 17
875:5x 5x 5x 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 3x 3x 5x 5x 7x 17 = 53550
Therefore, the value for common factors is 53550.
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 = 40046068912500/(1x53550)
LCM = 40046068912500/53550
LCM = 747825750
Thus, we can understand that the LCM of 343,918,855,170,875 is 747825750.
