Given numbers are 898,629,988,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,629,988,780 is 4185479220.
Find LCM of 898,629,988,780 with Prime Factorization
| 2 | 898, 629, 988, 780 |
| 2 | 449, 629, 494, 390 |
| 13 | 449, 629, 247, 195 |
| 449, 629, 19, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 449 x 629 x 19 x 15 = 4185479220
Therefore, the lowest common multiple of 898,629,988,780 is 4185479220.
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.
898 x 629 x 988 x 780 = 435289838880
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.
898 : 1, 2, 449, 898
629 : 1, 17, 37, 629
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,629,988,780, is 1.
Now, the common factors can be found like this.
898:2x 449
629:17x 37
988:2x 2x 13x 19
780:2x 2x 3x 5x 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 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 = 435289838880/(1x104)
LCM = 435289838880/104
LCM = 4185479220
Thus, we can understand that the LCM of 898,629,988,780 is 4185479220.
