Given numbers are 731,394,788,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,394,788,346 is 99652844.
Find LCM of 731,394,788,346 with Prime Factorization
| 2 | 731, 394, 788, 346 |
| 197 | 731, 197, 394, 173 |
| 731, 1, 2, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 197 x 731 x 1 x 2 x 173 = 99652844
Therefore, the lowest common multiple of 731,394,788,346 is 99652844.
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 394 x 788 x 346 = 78526441072
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
394 : 1, 2, 197, 394
788 : 1, 2, 4, 197, 394, 788
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,394,788,346, is 1.
Now, the common factors can be found like this.
731:17x 43
394:2x 197
788:2x 2x 197
346:2x 173
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 197 = 788
Therefore, the value for common factors is 788.
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 = 78526441072/(1x788)
LCM = 78526441072/788
LCM = 99652844
Thus, we can understand that the LCM of 731,394,788,346 is 99652844.
