Given numbers are 845,351,834,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,351,834,242 is 767450970.
Find LCM of 845,351,834,242 with Prime Factorization
2 | 845, 351, 834, 242 |
3 | 845, 351, 417, 121 |
13 | 845, 117, 139, 121 |
65, 9, 139, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 65 x 9 x 139 x 121 = 767450970
Therefore, the lowest common multiple of 845,351,834,242 is 767450970.
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.
845 x 351 x 834 x 242 = 59861175660
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.
845 : 1, 5, 13, 65, 169, 845
351 : 1, 3, 9, 13, 27, 39, 117, 351
834 : 1, 2, 3, 6, 139, 278, 417, 834
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,351,834,242, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
351:3x 3x 3x 13
834:2x 3x 139
242:2x 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 3x 13 = 78
Therefore, the value for common factors is 78.
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 = 59861175660/(1x78)
LCM = 59861175660/78
LCM = 767450970
Thus, we can understand that the LCM of 845,351,834,242 is 767450970.
