Given numbers are 786,977,856,713,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,977,856,713,403 is 3046447939704.
Find LCM of 786,977,856,713,403 with Prime Factorization
| 2 | 786, 977, 856, 713, 403 |
| 31 | 393, 977, 428, 713, 403 |
| 393, 977, 428, 23, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 393 x 977 x 428 x 23 x 13 = 3046447939704
Therefore, the lowest common multiple of 786,977,856,713,403 is 3046447939704.
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.
786 x 977 x 856 x 713 x 403 = 188879772261648
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
977 : 1, 977
856 : 1, 2, 4, 8, 107, 214, 428, 856
713 : 1, 23, 31, 713
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,977,856,713,403, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
977:977
856:2x 2x 2x 107
713:23x 31
403:13x 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 31 = 62
Therefore, the value for common factors is 62.
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 = 188879772261648/(1x62)
LCM = 188879772261648/62
LCM = 3046447939704
Thus, we can understand that the LCM of 786,977,856,713,403 is 3046447939704.
