Given numbers are 256,982,779,940,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,982,779,940,123 is 69031614720.
Find LCM of 256,982,779,940,123 with Prime Factorization
| 2 | 256, 982, 779, 940, 123 |
| 2 | 128, 491, 779, 470, 123 |
| 41 | 64, 491, 779, 235, 123 |
| 64, 491, 19, 235, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 64 x 491 x 19 x 235 x 3 = 69031614720
Therefore, the lowest common multiple of 256,982,779,940,123 is 69031614720.
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.
256 x 982 x 779 x 940 x 123 = 22642369628160
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
982 : 1, 2, 491, 982
779 : 1, 19, 41, 779
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,982,779,940,123, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
982:2x 491
779:19x 41
940:2x 2x 5x 47
123:3x 41
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 2x 41 = 328
Therefore, the value for common factors is 328.
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 = 22642369628160/(1x328)
LCM = 22642369628160/328
LCM = 69031614720
Thus, we can understand that the LCM of 256,982,779,940,123 is 69031614720.
