Given numbers are 299,202,420,845,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 299,202,420,845,811 is 133722983940.
Find LCM of 299,202,420,845,811 with Prime Factorization
| 2 | 299, 202, 420, 845, 811 |
| 5 | 299, 101, 210, 845, 811 |
| 13 | 299, 101, 42, 169, 811 |
| 23, 101, 42, 13, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 23 x 101 x 42 x 13 x 811 = 133722983940
Therefore, the lowest common multiple of 299,202,420,845,811 is 133722983940.
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.
299 x 202 x 420 x 845 x 811 = 17383987912200
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.
299 : 1, 13, 23, 299
202 : 1, 2, 101, 202
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
845 : 1, 5, 13, 65, 169, 845
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,202,420,845,811, is 1.
Now, the common factors can be found like this.
299:13x 23
202:2x 101
420:2x 2x 3x 5x 7
845:5x 13x 13
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 17383987912200/(1x130)
LCM = 17383987912200/130
LCM = 133722983940
Thus, we can understand that the LCM of 299,202,420,845,811 is 133722983940.
