The LCM of 782,459,927,731 is 93513906.
Find LCM of 782,459,927,731 with Prime Factorization
| 3 | 782, 459, 927, 731 |
| 3 | 782, 153, 309, 731 |
| 17 | 782, 51, 103, 731 |
| 46, 3, 103, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 46 x 3 x 103 x 43 = 93513906
Therefore, the lowest common multiple of 782,459,927,731 is 93513906.
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.
782 x 459 x 927 x 731 = 243229669506
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
459 : 1, 3, 9, 17, 27, 51, 153, 459
927 : 1, 3, 9, 103, 309, 927
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,459,927,731, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
459:3x 3x 3x 17
927:3x 3x 103
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17x 17 = 2601
Therefore, the value for common factors is 2601.
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 = 243229669506/(1x2601)
LCM = 243229669506/2601
LCM = 93513906
Thus, we can understand that the LCM of 782,459,927,731 is 93513906.
