Given numbers are 409,525,802,280,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,525,802,280,187 is 128812668600.
Find LCM of 409,525,802,280,187 with Prime Factorization
| 2 | 409, 525, 802, 280, 187 |
| 5 | 409, 525, 401, 140, 187 |
| 7 | 409, 105, 401, 28, 187 |
| 409, 15, 401, 4, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 409 x 15 x 401 x 4 x 187 = 128812668600
Therefore, the lowest common multiple of 409,525,802,280,187 is 128812668600.
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 525 x 802 x 280 x 187 = 9016886802000
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
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
802 : 1, 2, 401, 802
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,525,802,280,187, is 1.
Now, the common factors can be found like this.
409:409
525:3x 5x 5x 7
802:2x 401
280:2x 2x 2x 5x 7
187:11x 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 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 9016886802000/(1x70)
LCM = 9016886802000/70
LCM = 128812668600
Thus, we can understand that the LCM of 409,525,802,280,187 is 128812668600.
