Find LCM of 698,458,756,243,974 with Prime Factorization
| 2 | 698, 458, 756, 243, 974 |
| 3 | 349, 229, 378, 243, 487 |
| 3 | 349, 229, 126, 81, 487 |
| 3 | 349, 229, 42, 27, 487 |
| 349, 229, 14, 9, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 349 x 229 x 14 x 9 x 487 = 264822069708
Therefore, the lowest common multiple of 698,458,756,243,974 is 264822069708.
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.
698 x 458 x 756 x 243 x 974 = 57201567056928
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.
698 : 1, 2, 349, 698
458 : 1, 2, 229, 458
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
243 : 1, 3, 9, 27, 81, 243
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,458,756,243,974, is 1.
Now, the common factors can be found like this.
698:2x 349
458:2x 229
756:2x 2x 3x 3x 3x 7
243:3x 3x 3x 3x 3
974:2x 487
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 57201567056928/(1x216)
LCM = 57201567056928/216
LCM = 264822069708
Thus, we can understand that the LCM of 698,458,756,243,974 is 264822069708.
