Given numbers are 819,988,299,446
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,988,299,446 is 319249476.
Find LCM of 819,988,299,446 with Prime Factorization
| 2 | 819, 988, 299, 446 |
| 13 | 819, 494, 299, 223 |
| 63, 38, 23, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 63 x 38 x 23 x 223 = 319249476
Therefore, the lowest common multiple of 819,988,299,446 is 319249476.
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.
819 x 988 x 299 x 446 = 107906322888
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
299 : 1, 13, 23, 299
446 : 1, 2, 223, 446
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,988,299,446, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
988:2x 2x 13x 19
299:13x 23
446:2x 223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 107906322888/(1x338)
LCM = 107906322888/338
LCM = 319249476
Thus, we can understand that the LCM of 819,988,299,446 is 319249476.
