Find LCM of 493,556,774,678,731 with Prime Factorization
| 2 | 493, 556, 774, 678, 731 |
| 3 | 493, 278, 387, 339, 731 |
| 17 | 493, 278, 129, 113, 731 |
| 43 | 29, 278, 129, 113, 43 |
| 29, 278, 3, 113, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 43 x 29 x 278 x 3 x 113 x 1 = 11987016948
Therefore, the lowest common multiple of 493,556,774,678,731 is 11987016948.
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.
493 x 556 x 774 x 678 x 731 = 105150112667856
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.
493 : 1, 17, 29, 493
556 : 1, 2, 4, 139, 278, 556
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
678 : 1, 2, 3, 6, 113, 226, 339, 678
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,556,774,678,731, is 1.
Now, the common factors can be found like this.
493:17x 29
556:2x 2x 139
774:2x 3x 3x 43
678:2x 3x 113
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.
2x 2x 3x 17x 43 = 8772
Therefore, the value for common factors is 8772.
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 = 105150112667856/(1x8772)
LCM = 105150112667856/8772
LCM = 11987016948
Thus, we can understand that the LCM of 493,556,774,678,731 is 11987016948.
