Find LCM of 418,481,176,987,688 with Prime Factorization
| 2 | 418, 481, 176, 987, 688 |
| 2 | 209, 481, 88, 987, 344 |
| 2 | 209, 481, 44, 987, 172 |
| 2 | 209, 481, 22, 987, 86 |
| 11 | 209, 481, 11, 987, 43 |
| 19, 481, 1, 987, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 19 x 481 x 1 x 987 x 43 = 68264820624
Therefore, the lowest common multiple of 418,481,176,987,688 is 68264820624.
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.
418 x 481 x 176 x 987 x 688 = 24029216859648
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
481 : 1, 13, 37, 481
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
987 : 1, 3, 7, 21, 47, 141, 329, 987
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,481,176,987,688, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
481:13x 37
176:2x 2x 2x 2x 11
987:3x 7x 47
688:2x 2x 2x 2x 43
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 2x 2x 11 = 352
Therefore, the value for common factors is 352.
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 = 24029216859648/(1x352)
LCM = 24029216859648/352
LCM = 68264820624
Thus, we can understand that the LCM of 418,481,176,987,688 is 68264820624.
