Given numbers are 468,656,865,506,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,656,865,506,781 is 1192572192240.
Find LCM of 468,656,865,506,781 with Prime Factorization
| 2 | 468, 656, 865, 506, 781 |
| 2 | 234, 328, 865, 253, 781 |
| 11 | 117, 164, 865, 253, 781 |
| 117, 164, 865, 23, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 117 x 164 x 865 x 23 x 71 = 1192572192240
Therefore, the lowest common multiple of 468,656,865,506,781 is 1192572192240.
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.
468 x 656 x 865 x 506 x 781 = 104946352917120
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
865 : 1, 5, 173, 865
506 : 1, 2, 11, 22, 23, 46, 253, 506
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,656,865,506,781, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
656:2x 2x 2x 2x 41
865:5x 173
506:2x 11x 23
781:11x 71
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 11 = 88
Therefore, the value for common factors is 88.
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 = 104946352917120/(1x88)
LCM = 104946352917120/88
LCM = 1192572192240
Thus, we can understand that the LCM of 468,656,865,506,781 is 1192572192240.
