Given numbers are 902,794,405,686,153
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,794,405,686,153 is 845658676170.
Find LCM of 902,794,405,686,153 with Prime Factorization
| 2 | 902, 794, 405, 686, 153 |
| 3 | 451, 397, 405, 343, 153 |
| 3 | 451, 397, 135, 343, 51 |
| 451, 397, 45, 343, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 451 x 397 x 45 x 343 x 17 = 845658676170
Therefore, the lowest common multiple of 902,794,405,686,153 is 845658676170.
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.
902 x 794 x 405 x 686 x 153 = 30443712342120
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
794 : 1, 2, 397, 794
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
686 : 1, 2, 7, 14, 49, 98, 343, 686
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,794,405,686,153, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
794:2x 397
405:3x 3x 3x 3x 5
686:2x 7x 7x 7
153:3x 3x 17
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 30443712342120/(1x36)
LCM = 30443712342120/36
LCM = 845658676170
Thus, we can understand that the LCM of 902,794,405,686,153 is 845658676170.
