Given numbers are 409,925,684,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,925,684,720 is 1035097200.
Find LCM of 409,925,684,720 with Prime Factorization
| 2 | 409, 925, 684, 720 |
| 2 | 409, 925, 342, 360 |
| 3 | 409, 925, 171, 180 |
| 3 | 409, 925, 57, 60 |
| 5 | 409, 925, 19, 20 |
| 409, 185, 19, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 409 x 185 x 19 x 4 = 1035097200
Therefore, the lowest common multiple of 409,925,684,720 is 1035097200.
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.
409 x 925 x 684 x 720 = 186317496000
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.
409 : 1, 409
925 : 1, 5, 25, 37, 185, 925
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,925,684,720, is 1.
Now, the common factors can be found like this.
409:409
925:5x 5x 37
684:2x 2x 3x 3x 19
720:2x 2x 2x 2x 3x 3x 5
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 186317496000/(1x180)
LCM = 186317496000/180
LCM = 1035097200
Thus, we can understand that the LCM of 409,925,684,720 is 1035097200.
