Given numbers are 556,851,256,687,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,851,256,687,831 is 5762631273216.
Find LCM of 556,851,256,687,831 with Prime Factorization
| 2 | 556, 851, 256, 687, 831 |
| 2 | 278, 851, 128, 687, 831 |
| 3 | 139, 851, 64, 687, 831 |
| 139, 851, 64, 229, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 139 x 851 x 64 x 229 x 277 = 5762631273216
Therefore, the lowest common multiple of 556,851,256,687,831 is 5762631273216.
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.
556 x 851 x 256 x 687 x 831 = 69151575278592
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.
556 : 1, 2, 4, 139, 278, 556
851 : 1, 23, 37, 851
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
687 : 1, 3, 229, 687
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,851,256,687,831, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
851:23x 37
256:2x 2x 2x 2x 2x 2x 2x 2
687:3x 229
831:3x 277
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 3 = 12
Therefore, the value for common factors is 12.
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 = 69151575278592/(1x12)
LCM = 69151575278592/12
LCM = 5762631273216
Thus, we can understand that the LCM of 556,851,256,687,831 is 5762631273216.
