Given numbers are 821,159,935,887,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,159,935,887,442 is 2814808540830.
Find LCM of 821,159,935,887,442 with Prime Factorization
| 17 | 821, 159, 935, 887, 442 |
| 821, 159, 55, 887, 26 |
Multiply the prime numbers at the bottom and the left side.
17 x 821 x 159 x 55 x 887 x 26 = 2814808540830
Therefore, the lowest common multiple of 821,159,935,887,442 is 2814808540830.
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.
821 x 159 x 935 x 887 x 442 = 47851745194110
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.
821 : 1, 821
159 : 1, 3, 53, 159
935 : 1, 5, 11, 17, 55, 85, 187, 935
887 : 1, 887
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,159,935,887,442, is 1.
Now, the common factors can be found like this.
821:821
159:3x 53
935:5x 11x 17
887:887
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 47851745194110/(1x17)
LCM = 47851745194110/17
LCM = 2814808540830
Thus, we can understand that the LCM of 821,159,935,887,442 is 2814808540830.
