Given numbers are 781,781,302,894,415
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,781,302,894,415 is 43753580310.
Find LCM of 781,781,302,894,415 with Prime Factorization
| 2 | 781, 781, 302, 894, 415 |
| 11 | 781, 781, 151, 447, 415 |
| 71 | 71, 71, 151, 447, 415 |
| 1, 1, 151, 447, 415 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 1 x 1 x 151 x 447 x 415 = 43753580310
Therefore, the lowest common multiple of 781,781,302,894,415 is 43753580310.
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 781 x 302 x 894 x 415 = 68343092444220
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
781 : 1, 11, 71, 781
302 : 1, 2, 151, 302
894 : 1, 2, 3, 6, 149, 298, 447, 894
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,781,302,894,415, is 1.
Now, the common factors can be found like this.
781:11x 71
781:11x 71
302:2x 151
894:2x 3x 149
415:5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 71 = 1562
Therefore, the value for common factors is 1562.
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 = 68343092444220/(1x1562)
LCM = 68343092444220/1562
LCM = 43753580310
Thus, we can understand that the LCM of 781,781,302,894,415 is 43753580310.
