Given numbers are 456,731,786,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 456,731,786,857 is 37422632712.
Find LCM of 456,731,786,857 with Prime Factorization
| 2 | 456, 731, 786, 857 |
| 3 | 228, 731, 393, 857 |
| 76, 731, 131, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 76 x 731 x 131 x 857 = 37422632712
Therefore, the lowest common multiple of 456,731,786,857 is 37422632712.
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.
456 x 731 x 786 x 857 = 224535796272
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
731 : 1, 17, 43, 731
786 : 1, 2, 3, 6, 131, 262, 393, 786
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,731,786,857, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
731:17x 43
786:2x 3x 131
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 224535796272/(1x6)
LCM = 224535796272/6
LCM = 37422632712
Thus, we can understand that the LCM of 456,731,786,857 is 37422632712.
