Given numbers are 831,890,362,393,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,890,362,393,870 is 508556136210.
Find LCM of 831,890,362,393,870 with Prime Factorization
| 2 | 831, 890, 362, 393, 870 |
| 3 | 831, 445, 181, 393, 435 |
| 5 | 277, 445, 181, 131, 145 |
| 277, 89, 181, 131, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 277 x 89 x 181 x 131 x 29 = 508556136210
Therefore, the lowest common multiple of 831,890,362,393,870 is 508556136210.
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.
831 x 890 x 362 x 393 x 870 = 91540104517800
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.
831 : 1, 3, 277, 831
890 : 1, 2, 5, 10, 89, 178, 445, 890
362 : 1, 2, 181, 362
393 : 1, 3, 131, 393
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,890,362,393,870, is 1.
Now, the common factors can be found like this.
831:3x 277
890:2x 5x 89
362:2x 181
393:3x 131
870:2x 3x 5x 29
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 = 91540104517800/(1x180)
LCM = 91540104517800/180
LCM = 508556136210
Thus, we can understand that the LCM of 831,890,362,393,870 is 508556136210.
