Given numbers are 823,489,391,326,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 823,489,391,326,248 is 39024480696.
Find LCM of 823,489,391,326,248 with Prime Factorization
| 2 | 823, 489, 391, 326, 248 |
| 163 | 823, 489, 391, 163, 124 |
| 823, 3, 391, 1, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 163 x 823 x 3 x 391 x 1 x 124 = 39024480696
Therefore, the lowest common multiple of 823,489,391,326,248 is 39024480696.
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.
823 x 489 x 391 x 326 x 248 = 12721980706896
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.
823 : 1, 823
489 : 1, 3, 163, 489
391 : 1, 17, 23, 391
326 : 1, 2, 163, 326
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,489,391,326,248, is 1.
Now, the common factors can be found like this.
823:823
489:3x 163
391:17x 23
326:2x 163
248:2x 2x 2x 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 163 = 326
Therefore, the value for common factors is 326.
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 = 12721980706896/(1x326)
LCM = 12721980706896/326
LCM = 39024480696
Thus, we can understand that the LCM of 823,489,391,326,248 is 39024480696.
