Given numbers are 478,812,988,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,812,988,897 is 3307500924.
Find LCM of 478,812,988,897 with Prime Factorization
| 2 | 478, 812, 988, 897 |
| 2 | 239, 406, 494, 897 |
| 13 | 239, 203, 247, 897 |
| 239, 203, 19, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 239 x 203 x 19 x 69 = 3307500924
Therefore, the lowest common multiple of 478,812,988,897 is 3307500924.
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.
478 x 812 x 988 x 897 = 343980096096
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.
478 : 1, 2, 239, 478
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
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,812,988,897, is 1.
Now, the common factors can be found like this.
478:2x 239
812:2x 2x 7x 29
988:2x 2x 13x 19
897:3x 13x 23
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 13 = 104
Therefore, the value for common factors is 104.
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 = 343980096096/(1x104)
LCM = 343980096096/104
LCM = 3307500924
Thus, we can understand that the LCM of 478,812,988,897 is 3307500924.
