Given numbers are 781,706,771,407,468
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,706,771,407,468 is 1226892296916.
Find LCM of 781,706,771,407,468 with Prime Factorization
| 2 | 781, 706, 771, 407, 468 |
| 3 | 781, 353, 771, 407, 234 |
| 11 | 781, 353, 257, 407, 78 |
| 71, 353, 257, 37, 78 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 71 x 353 x 257 x 37 x 78 = 1226892296916
Therefore, the lowest common multiple of 781,706,771,407,468 is 1226892296916.
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.
781 x 706 x 771 x 407 x 468 = 80974891596456
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.
781 : 1, 11, 71, 781
706 : 1, 2, 353, 706
771 : 1, 3, 257, 771
407 : 1, 11, 37, 407
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,706,771,407,468, is 1.
Now, the common factors can be found like this.
781:11x 71
706:2x 353
771:3x 257
407:11x 37
468:2x 2x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 80974891596456/(1x66)
LCM = 80974891596456/66
LCM = 1226892296916
Thus, we can understand that the LCM of 781,706,771,407,468 is 1226892296916.
