Find LCM of 357,403,351,378 with Prime Factorization
| 3 | 357, 403, 351, 378 |
| 3 | 119, 403, 117, 126 |
| 3 | 119, 403, 39, 42 |
| 7 | 119, 403, 13, 14 |
| 13 | 17, 403, 13, 2 |
| 17, 31, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 13 x 17 x 31 x 1 x 2 = 2589678
Therefore, the lowest common multiple of 357,403,351,378 is 2589678.
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 403 x 351 x 378 = 19088516538
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
403 : 1, 13, 31, 403
351 : 1, 3, 9, 13, 27, 39, 117, 351
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,403,351,378, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
403:13x 31
351:3x 3x 3x 13
378:2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7x 13 = 7371
Therefore, the value for common factors is 7371.
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 = 19088516538/(1x7371)
LCM = 19088516538/7371
LCM = 2589678
Thus, we can understand that the LCM of 357,403,351,378 is 2589678.
