Given numbers are 680,886,828,979,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,886,828,979,121 is 671519086920.
Find LCM of 680,886,828,979,121 with Prime Factorization
| 2 | 680, 886, 828, 979, 121 |
| 2 | 340, 443, 414, 979, 121 |
| 11 | 170, 443, 207, 979, 121 |
| 170, 443, 207, 89, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 170 x 443 x 207 x 89 x 11 = 671519086920
Therefore, the lowest common multiple of 680,886,828,979,121 is 671519086920.
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.
680 x 886 x 828 x 979 x 121 = 59093679648960
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
886 : 1, 2, 443, 886
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
979 : 1, 11, 89, 979
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,886,828,979,121, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
886:2x 443
828:2x 2x 3x 3x 23
979:11x 89
121:11x 11
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 2x 11 = 88
Therefore, the value for common factors is 88.
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 = 59093679648960/(1x88)
LCM = 59093679648960/88
LCM = 671519086920
Thus, we can understand that the LCM of 680,886,828,979,121 is 671519086920.
