Given numbers are 391,751,629,947,552
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,751,629,947,552 is 246933287976.
Find LCM of 391,751,629,947,552 with Prime Factorization
| 17 | 391, 751, 629, 947, 552 |
| 23 | 23, 751, 37, 947, 552 |
| 1, 751, 37, 947, 24 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 1 x 751 x 37 x 947 x 24 = 246933287976
Therefore, the lowest common multiple of 391,751,629,947,552 is 246933287976.
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.
391 x 751 x 629 x 947 x 552 = 96550915598616
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.
391 : 1, 17, 23, 391
751 : 1, 751
629 : 1, 17, 37, 629
947 : 1, 947
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,751,629,947,552, is 1.
Now, the common factors can be found like this.
391:17x 23
751:751
629:17x 37
947:947
552:2x 2x 2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
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 = 96550915598616/(1x391)
LCM = 96550915598616/391
LCM = 246933287976
Thus, we can understand that the LCM of 391,751,629,947,552 is 246933287976.
