Given numbers are 839,147,215,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,147,215,831 is 7345096815.
Find LCM of 839,147,215,831 with Prime Factorization
3 | 839, 147, 215, 831 |
839, 49, 215, 277 |
Multiply the prime numbers at the bottom and the left side.
3 x 839 x 49 x 215 x 277 = 7345096815
Therefore, the lowest common multiple of 839,147,215,831 is 7345096815.
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.
839 x 147 x 215 x 831 = 22035290445
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.
839 : 1, 839
147 : 1, 3, 7, 21, 49, 147
215 : 1, 5, 43, 215
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,147,215,831, is 1.
Now, the common factors can be found like this.
839:839
147:3x 7x 7
215:5x 43
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.
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 = 22035290445/(1x3)
LCM = 22035290445/3
LCM = 7345096815
Thus, we can understand that the LCM of 839,147,215,831 is 7345096815.
