Given numbers are 788,946,731,694
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,946,731,694 is 2198698876.
Find LCM of 788,946,731,694 with Prime Factorization
| 2 | 788, 946, 731, 694 |
| 43 | 394, 473, 731, 347 |
| 394, 11, 17, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 394 x 11 x 17 x 347 = 2198698876
Therefore, the lowest common multiple of 788,946,731,694 is 2198698876.
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.
788 x 946 x 731 x 694 = 378176206672
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.
788 : 1, 2, 4, 197, 394, 788
946 : 1, 2, 11, 22, 43, 86, 473, 946
731 : 1, 17, 43, 731
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,946,731,694, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
946:2x 11x 43
731:17x 43
694:2x 347
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 43 = 172
Therefore, the value for common factors is 172.
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 = 378176206672/(1x172)
LCM = 378176206672/172
LCM = 2198698876
Thus, we can understand that the LCM of 788,946,731,694 is 2198698876.
