Find LCM of 124,684,988,918,447 with Prime Factorization
| 2 | 124, 684, 988, 918, 447 |
| 2 | 62, 342, 494, 459, 447 |
| 3 | 31, 171, 247, 459, 447 |
| 3 | 31, 57, 247, 153, 149 |
| 19 | 31, 19, 247, 51, 149 |
| 31, 1, 13, 51, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 31 x 1 x 13 x 51 x 149 = 2094679548
Therefore, the lowest common multiple of 124,684,988,918,447 is 2094679548.
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.
124 x 684 x 988 x 918 x 447 = 34386259459968
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.
124 : 1, 2, 4, 31, 62, 124
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,684,988,918,447, is 1.
Now, the common factors can be found like this.
124:2x 2x 31
684:2x 2x 3x 3x 19
988:2x 2x 13x 19
918:2x 3x 3x 3x 17
447:3x 149
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 3x 3x 3x 19 = 16416
Therefore, the value for common factors is 16416.
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 = 34386259459968/(1x16416)
LCM = 34386259459968/16416
LCM = 2094679548
Thus, we can understand that the LCM of 124,684,988,918,447 is 2094679548.
