Given numbers are 377,815,663,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 377,815,663,731 is 673810215.
Find LCM of 377,815,663,731 with Prime Factorization
| 13 | 377, 815, 663, 731 |
| 17 | 29, 815, 51, 731 |
| 29, 815, 3, 43 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 29 x 815 x 3 x 43 = 673810215
Therefore, the lowest common multiple of 377,815,663,731 is 673810215.
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.
377 x 815 x 663 x 731 = 148912057515
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.
377 : 1, 13, 29, 377
815 : 1, 5, 163, 815
663 : 1, 3, 13, 17, 39, 51, 221, 663
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,815,663,731, is 1.
Now, the common factors can be found like this.
377:13x 29
815:5x 163
663:3x 13x 17
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 148912057515/(1x221)
LCM = 148912057515/221
LCM = 673810215
Thus, we can understand that the LCM of 377,815,663,731 is 673810215.
