Given numbers are 299,136,578,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 299,136,578,806 is 21429928.
Find LCM of 299,136,578,806 with Prime Factorization
| 2 | 299, 136, 578, 806 |
| 13 | 299, 68, 289, 403 |
| 17 | 23, 68, 289, 31 |
| 23, 4, 17, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 23 x 4 x 17 x 31 = 21429928
Therefore, the lowest common multiple of 299,136,578,806 is 21429928.
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 136 x 578 x 806 = 18944056352
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
136 : 1, 2, 4, 8, 17, 34, 68, 136
578 : 1, 2, 17, 34, 289, 578
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 299,136,578,806, is 1.
Now, the common factors can be found like this.
299:13x 23
136:2x 2x 2x 17
578:2x 17x 17
806:2x 13x 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 13x 17 = 884
Therefore, the value for common factors is 884.
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 = 18944056352/(1x884)
LCM = 18944056352/884
LCM = 21429928
Thus, we can understand that the LCM of 299,136,578,806 is 21429928.
