Find LCM of 357,285,442,970,218 with Prime Factorization
| 2 | 357, 285, 442, 970, 218 |
| 3 | 357, 285, 221, 485, 109 |
| 5 | 119, 95, 221, 485, 109 |
| 17 | 119, 19, 221, 97, 109 |
| 7, 19, 13, 97, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 7 x 19 x 13 x 97 x 109 = 9323165670
Therefore, the lowest common multiple of 357,285,442,970,218 is 9323165670.
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.
357 x 285 x 442 x 970 x 218 = 9509628983400
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
285 : 1, 3, 5, 15, 19, 57, 95, 285
442 : 1, 2, 13, 17, 26, 34, 221, 442
970 : 1, 2, 5, 10, 97, 194, 485, 970
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,285,442,970,218, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
285:3x 5x 19
442:2x 13x 17
970:2x 5x 97
218:2x 109
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 5x 17 = 1020
Therefore, the value for common factors is 1020.
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 = 9509628983400/(1x1020)
LCM = 9509628983400/1020
LCM = 9323165670
Thus, we can understand that the LCM of 357,285,442,970,218 is 9323165670.
