Given numbers are 794,840,831,454,465
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 794,840,831,454,465 is 650035556520.
Find LCM of 794,840,831,454,465 with Prime Factorization
| 2 | 794, 840, 831, 454, 465 |
| 3 | 397, 420, 831, 227, 465 |
| 5 | 397, 140, 277, 227, 155 |
| 397, 28, 277, 227, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 397 x 28 x 277 x 227 x 31 = 650035556520
Therefore, the lowest common multiple of 794,840,831,454,465 is 650035556520.
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.
794 x 840 x 831 x 454 x 465 = 117006400173600
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.
794 : 1, 2, 397, 794
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
831 : 1, 3, 277, 831
454 : 1, 2, 227, 454
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,840,831,454,465, is 1.
Now, the common factors can be found like this.
794:2x 397
840:2x 2x 2x 3x 5x 7
831:3x 277
454:2x 227
465:3x 5x 31
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 117006400173600/(1x180)
LCM = 117006400173600/180
LCM = 650035556520
Thus, we can understand that the LCM of 794,840,831,454,465 is 650035556520.
