Given numbers are 813,457,875,686,914
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,457,875,686,914 is 31859640750.
Find LCM of 813,457,875,686,914 with Prime Factorization
| 2 | 813, 457, 875, 686, 914 |
| 7 | 813, 457, 875, 343, 457 |
| 457 | 813, 457, 125, 49, 457 |
| 813, 1, 125, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 457 x 813 x 1 x 125 x 49 x 1 = 31859640750
Therefore, the lowest common multiple of 813,457,875,686,914 is 31859640750.
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.
813 x 457 x 875 x 686 x 914 = 203837981518500
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.
813 : 1, 3, 271, 813
457 : 1, 457
875 : 1, 5, 7, 25, 35, 125, 175, 875
686 : 1, 2, 7, 14, 49, 98, 343, 686
914 : 1, 2, 457, 914
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,457,875,686,914, is 1.
Now, the common factors can be found like this.
813:3x 271
457:457
875:5x 5x 5x 7
686:2x 7x 7x 7
914:2x 457
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 457 = 6398
Therefore, the value for common factors is 6398.
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 = 203837981518500/(1x6398)
LCM = 203837981518500/6398
LCM = 31859640750
Thus, we can understand that the LCM of 813,457,875,686,914 is 31859640750.
