The LCM of 218,812,988,637,208 is 612121328.
Find LCM of 218,812,988,637,208 with Prime Factorization
| 2 | 218, 812, 988, 637, 208 |
| 2 | 109, 406, 494, 637, 104 |
| 7 | 109, 203, 247, 637, 52 |
| 13 | 109, 29, 247, 91, 52 |
| 109, 29, 19, 7, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 109 x 29 x 19 x 7 x 4 = 612121328
Therefore, the lowest common multiple of 218,812,988,637,208 is 612121328.
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.
218 x 812 x 988 x 637 x 208 = 23172464992768
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.
218 : 1, 2, 109, 218
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
637 : 1, 7, 13, 49, 91, 637
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,812,988,637,208, is 1.
Now, the common factors can be found like this.
218:2x 109
812:2x 2x 7x 29
988:2x 2x 13x 19
637:7x 7x 13
208:2x 2x 2x 2x 13
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 7x 13x 13 = 37856
Therefore, the value for common factors is 37856.
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 = 23172464992768/(1x37856)
LCM = 23172464992768/37856
LCM = 612121328
Thus, we can understand that the LCM of 218,812,988,637,208 is 612121328.
