The LCM of 731,951,207,476,434 is 41635780452.
Find LCM of 731,951,207,476,434 with Prime Factorization
| 2 | 731, 951, 207, 476, 434 |
| 3 | 731, 951, 207, 238, 217 |
| 7 | 731, 317, 69, 238, 217 |
| 17 | 731, 317, 69, 34, 31 |
| 43, 317, 69, 2, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 43 x 317 x 69 x 2 x 31 = 41635780452
Therefore, the lowest common multiple of 731,951,207,476,434 is 41635780452.
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.
731 x 951 x 207 x 476 x 434 = 29727947242728
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.
731 : 1, 17, 43, 731
951 : 1, 3, 317, 951
207 : 1, 3, 9, 23, 69, 207
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,951,207,476,434, is 1.
Now, the common factors can be found like this.
731:17x 43
951:3x 317
207:3x 3x 23
476:2x 2x 7x 17
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 17 = 714
Therefore, the value for common factors is 714.
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 = 29727947242728/(1x714)
LCM = 29727947242728/714
LCM = 41635780452
Thus, we can understand that the LCM of 731,951,207,476,434 is 41635780452.
