Given numbers are 681,258,545,943,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,258,545,943,731 is 511684992570.
Find LCM of 681,258,545,943,731 with Prime Factorization
| 3 | 681, 258, 545, 943, 731 |
| 43 | 227, 86, 545, 943, 731 |
| 227, 2, 545, 943, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 227 x 2 x 545 x 943 x 17 = 511684992570
Therefore, the lowest common multiple of 681,258,545,943,731 is 511684992570.
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.
681 x 258 x 545 x 943 x 731 = 66007364041530
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.
681 : 1, 3, 227, 681
258 : 1, 2, 3, 6, 43, 86, 129, 258
545 : 1, 5, 109, 545
943 : 1, 23, 41, 943
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,258,545,943,731, is 1.
Now, the common factors can be found like this.
681:3x 227
258:2x 3x 43
545:5x 109
943:23x 41
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.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 66007364041530/(1x129)
LCM = 66007364041530/129
LCM = 511684992570
Thus, we can understand that the LCM of 681,258,545,943,731 is 511684992570.
