Given numbers are 855,552,982,831,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,552,982,831,781 is 16710761188440.
Find LCM of 855,552,982,831,781 with Prime Factorization
| 2 | 855, 552, 982, 831, 781 |
| 3 | 855, 276, 491, 831, 781 |
| 285, 92, 491, 277, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 285 x 92 x 491 x 277 x 781 = 16710761188440
Therefore, the lowest common multiple of 855,552,982,831,781 is 16710761188440.
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.
855 x 552 x 982 x 831 x 781 = 300793701391920
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
982 : 1, 2, 491, 982
831 : 1, 3, 277, 831
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,552,982,831,781, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
552:2x 2x 2x 3x 23
982:2x 491
831:3x 277
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 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 300793701391920/(1x18)
LCM = 300793701391920/18
LCM = 16710761188440
Thus, we can understand that the LCM of 855,552,982,831,781 is 16710761188440.
