Given numbers are 898,634,840,991,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,634,840,991,291 is 11492917204440.
Find LCM of 898,634,840,991,291 with Prime Factorization
| 2 | 898, 634, 840, 991, 291 |
| 3 | 449, 317, 420, 991, 291 |
| 449, 317, 140, 991, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 449 x 317 x 140 x 991 x 97 = 11492917204440
Therefore, the lowest common multiple of 898,634,840,991,291 is 11492917204440.
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 634 x 840 x 991 x 291 = 137915006453280
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
634 : 1, 2, 317, 634
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
991 : 1, 991
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,634,840,991,291, is 1.
Now, the common factors can be found like this.
898:2x 449
634:2x 317
840:2x 2x 2x 3x 5x 7
991:991
291:3x 97
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 3 = 12
Therefore, the value for common factors is 12.
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 = 137915006453280/(1x12)
LCM = 137915006453280/12
LCM = 11492917204440
Thus, we can understand that the LCM of 898,634,840,991,291 is 11492917204440.
