Given numbers are 639,886,831,587,881
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,886,831,587,881 is 81101401410726.
Find LCM of 639,886,831,587,881 with Prime Factorization
| 3 | 639, 886, 831, 587, 881 |
| 213, 886, 277, 587, 881 |
Multiply the prime numbers at the bottom and the left side.
3 x 213 x 886 x 277 x 587 x 881 = 81101401410726
Therefore, the lowest common multiple of 639,886,831,587,881 is 81101401410726.
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.
639 x 886 x 831 x 587 x 881 = 243304204232178
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.
639 : 1, 3, 9, 71, 213, 639
886 : 1, 2, 443, 886
831 : 1, 3, 277, 831
587 : 1, 587
881 : 1, 881
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,886,831,587,881, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
886:2x 443
831:3x 277
587:587
881:881
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 243304204232178/(1x3)
LCM = 243304204232178/3
LCM = 81101401410726
Thus, we can understand that the LCM of 639,886,831,587,881 is 81101401410726.
