Given numbers are 115,615,810,137,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,615,810,137,980 is 10255181580.
Find LCM of 115,615,810,137,980 with Prime Factorization
| 2 | 115, 615, 810, 137, 980 |
| 3 | 115, 615, 405, 137, 490 |
| 5 | 115, 205, 135, 137, 490 |
| 23, 41, 27, 137, 98 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 41 x 27 x 137 x 98 = 10255181580
Therefore, the lowest common multiple of 115,615,810,137,980 is 10255181580.
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.
115 x 615 x 810 x 137 x 980 = 7691386185000
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.
115 : 1, 5, 23, 115
615 : 1, 3, 5, 15, 41, 123, 205, 615
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
137 : 1, 137
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,615,810,137,980, is 1.
Now, the common factors can be found like this.
115:5x 23
615:3x 5x 41
810:2x 3x 3x 3x 3x 5
137:137
980:2x 2x 5x 7x 7
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 5x 5x 5 = 750
Therefore, the value for common factors is 750.
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 = 7691386185000/(1x750)
LCM = 7691386185000/750
LCM = 10255181580
Thus, we can understand that the LCM of 115,615,810,137,980 is 10255181580.
