Given numbers are 898,531,981,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,531,981,392 is 10187167032.
Find LCM of 898,531,981,392 with Prime Factorization
| 2 | 898, 531, 981, 392 |
| 3 | 449, 531, 981, 196 |
| 3 | 449, 177, 327, 196 |
| 449, 59, 109, 196 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 449 x 59 x 109 x 196 = 10187167032
Therefore, the lowest common multiple of 898,531,981,392 is 10187167032.
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 531 x 981 x 392 = 183369006576
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
531 : 1, 3, 9, 59, 177, 531
981 : 1, 3, 9, 109, 327, 981
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,531,981,392, is 1.
Now, the common factors can be found like this.
898:2x 449
531:3x 3x 59
981:3x 3x 109
392:2x 2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 183369006576/(1x18)
LCM = 183369006576/18
LCM = 10187167032
Thus, we can understand that the LCM of 898,531,981,392 is 10187167032.
