Given numbers are 985,406,946,242,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,406,946,242,891 is 168539270130.
Find LCM of 985,406,946,242,891 with Prime Factorization
2 | 985, 406, 946, 242, 891 |
11 | 985, 203, 473, 121, 891 |
985, 203, 43, 11, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 985 x 203 x 43 x 11 x 81 = 168539270130
Therefore, the lowest common multiple of 985,406,946,242,891 is 168539270130.
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.
985 x 406 x 946 x 242 x 891 = 81573006742920
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.
985 : 1, 5, 197, 985
406 : 1, 2, 7, 14, 29, 58, 203, 406
946 : 1, 2, 11, 22, 43, 86, 473, 946
242 : 1, 2, 11, 22, 121, 242
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,406,946,242,891, is 1.
Now, the common factors can be found like this.
985:5x 197
406:2x 7x 29
946:2x 11x 43
242:2x 11x 11
891:3x 3x 3x 3x 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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 81573006742920/(1x484)
LCM = 81573006742920/484
LCM = 168539270130
Thus, we can understand that the LCM of 985,406,946,242,891 is 168539270130.
