Find LCM of 387,154,504,458,418 with Prime Factorization
| 2 | 387, 154, 504, 458, 418 |
| 3 | 387, 77, 252, 229, 209 |
| 3 | 129, 77, 84, 229, 209 |
| 7 | 43, 77, 28, 229, 209 |
| 11 | 43, 11, 4, 229, 209 |
| 43, 1, 4, 229, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 11 x 43 x 1 x 4 x 229 x 19 = 1037243592
Therefore, the lowest common multiple of 387,154,504,458,418 is 1037243592.
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.
387 x 154 x 504 x 458 x 418 = 5750478474048
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.
387 : 1, 3, 9, 43, 129, 387
154 : 1, 2, 7, 11, 14, 22, 77, 154
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
458 : 1, 2, 229, 458
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,154,504,458,418, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
154:2x 7x 11
504:2x 2x 2x 3x 3x 7
458:2x 229
418:2x 11x 19
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 3x 3x 7x 11 = 5544
Therefore, the value for common factors is 5544.
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 = 5750478474048/(1x5544)
LCM = 5750478474048/5544
LCM = 1037243592
Thus, we can understand that the LCM of 387,154,504,458,418 is 1037243592.
