Find LCM of 608,561,731,484,947 with Prime Factorization
| 2 | 608, 561, 731, 484, 947 |
| 2 | 304, 561, 731, 242, 947 |
| 11 | 152, 561, 731, 121, 947 |
| 17 | 152, 51, 731, 11, 947 |
| 152, 3, 43, 11, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 152 x 3 x 43 x 11 x 947 = 152783888928
Therefore, the lowest common multiple of 608,561,731,484,947 is 152783888928.
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.
608 x 561 x 731 x 484 x 947 = 114282348918144
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.
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
561 : 1, 3, 11, 17, 33, 51, 187, 561
731 : 1, 17, 43, 731
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 608,561,731,484,947, is 1.
Now, the common factors can be found like this.
608:2x 2x 2x 2x 2x 19
561:3x 11x 17
731:17x 43
484:2x 2x 11x 11
947:947
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 114282348918144/(1x748)
LCM = 114282348918144/748
LCM = 152783888928
Thus, we can understand that the LCM of 608,561,731,484,947 is 152783888928.
