Given numbers are 831,955,744,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,955,744,431 is 84826851240.
Find LCM of 831,955,744,431 with Prime Factorization
| 3 | 831, 955, 744, 431 |
| 277, 955, 248, 431 |
Multiply the prime numbers at the bottom and the left side.
3 x 277 x 955 x 248 x 431 = 84826851240
Therefore, the lowest common multiple of 831,955,744,431 is 84826851240.
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.
831 x 955 x 744 x 431 = 254480553720
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.
831 : 1, 3, 277, 831
955 : 1, 5, 191, 955
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,955,744,431, is 1.
Now, the common factors can be found like this.
831:3x 277
955:5x 191
744:2x 2x 2x 3x 31
431:431
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 = 254480553720/(1x3)
LCM = 254480553720/3
LCM = 84826851240
Thus, we can understand that the LCM of 831,955,744,431 is 84826851240.
