Given numbers are 840,517,629,706,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,517,629,706,395 is 7617672040440.
Find LCM of 840,517,629,706,395 with Prime Factorization
2 | 840, 517, 629, 706, 395 |
5 | 420, 517, 629, 353, 395 |
84, 517, 629, 353, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 84 x 517 x 629 x 353 x 79 = 7617672040440
Therefore, the lowest common multiple of 840,517,629,706,395 is 7617672040440.
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.
840 x 517 x 629 x 706 x 395 = 76176720404400
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
517 : 1, 11, 47, 517
629 : 1, 17, 37, 629
706 : 1, 2, 353, 706
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,517,629,706,395, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
517:11x 47
629:17x 37
706:2x 353
395:5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 76176720404400/(1x10)
LCM = 76176720404400/10
LCM = 7617672040440
Thus, we can understand that the LCM of 840,517,629,706,395 is 7617672040440.
