Given numbers are 514,771,398,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 514,771,398,686 is 105252294.
Find LCM of 514,771,398,686 with Prime Factorization
| 2 | 514, 771, 398, 686 |
| 257 | 257, 771, 199, 343 |
| 1, 3, 199, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 257 x 1 x 3 x 199 x 343 = 105252294
Therefore, the lowest common multiple of 514,771,398,686 is 105252294.
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.
514 x 771 x 398 x 686 = 108199358232
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.
514 : 1, 2, 257, 514
771 : 1, 3, 257, 771
398 : 1, 2, 199, 398
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 514,771,398,686, is 1.
Now, the common factors can be found like this.
514:2x 257
771:3x 257
398:2x 199
686:2x 7x 7x 7
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 257 = 1028
Therefore, the value for common factors is 1028.
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 = 108199358232/(1x1028)
LCM = 108199358232/1028
LCM = 105252294
Thus, we can understand that the LCM of 514,771,398,686 is 105252294.
