Given numbers are 517,972,568,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,972,568,691 is 49308659928.
Find LCM of 517,972,568,691 with Prime Factorization
| 2 | 517, 972, 568, 691 |
| 2 | 517, 486, 284, 691 |
| 517, 243, 142, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 517 x 243 x 142 x 691 = 49308659928
Therefore, the lowest common multiple of 517,972,568,691 is 49308659928.
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.
517 x 972 x 568 x 691 = 197234639712
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.
517 : 1, 11, 47, 517
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
568 : 1, 2, 4, 8, 71, 142, 284, 568
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,972,568,691, is 1.
Now, the common factors can be found like this.
517:11x 47
972:2x 2x 3x 3x 3x 3x 3
568:2x 2x 2x 71
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 197234639712/(1x4)
LCM = 197234639712/4
LCM = 49308659928
Thus, we can understand that the LCM of 517,972,568,691 is 49308659928.
