Given numbers are 605,779,123,892,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,779,123,892,646 is 21440152140.
Find LCM of 605,779,123,892,646 with Prime Factorization
| 2 | 605, 779, 123, 892, 646 |
| 19 | 605, 779, 123, 446, 323 |
| 41 | 605, 41, 123, 446, 17 |
| 605, 1, 3, 446, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 41 x 605 x 1 x 3 x 446 x 17 = 21440152140
Therefore, the lowest common multiple of 605,779,123,892,646 is 21440152140.
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.
605 x 779 x 123 x 892 x 646 = 33403757034120
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.
605 : 1, 5, 11, 55, 121, 605
779 : 1, 19, 41, 779
123 : 1, 3, 41, 123
892 : 1, 2, 4, 223, 446, 892
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,779,123,892,646, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
779:19x 41
123:3x 41
892:2x 2x 223
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 41 = 1558
Therefore, the value for common factors is 1558.
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 = 33403757034120/(1x1558)
LCM = 33403757034120/1558
LCM = 21440152140
Thus, we can understand that the LCM of 605,779,123,892,646 is 21440152140.
