Given numbers are 393,107,856,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,107,856,809 is 272154072.
Find LCM of 393,107,856,809 with Prime Factorization
107 | 393, 107, 856, 809 |
393, 1, 8, 809 |
Multiply the prime numbers at the bottom and the left side.
107 x 393 x 1 x 8 x 809 = 272154072
Therefore, the lowest common multiple of 393,107,856,809 is 272154072.
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.
393 x 107 x 856 x 809 = 29120485704
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.
393 : 1, 3, 131, 393
107 : 1, 107
856 : 1, 2, 4, 8, 107, 214, 428, 856
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,107,856,809, is 1.
Now, the common factors can be found like this.
393:3x 131
107:107
856:2x 2x 2x 107
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
107 = 107
Therefore, the value for common factors is 107.
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 = 29120485704/(1x107)
LCM = 29120485704/107
LCM = 272154072
Thus, we can understand that the LCM of 393,107,856,809 is 272154072.
