Find LCM of 920,285,247,715,813 with Prime Factorization
| 3 | 920, 285, 247, 715, 813 |
| 5 | 920, 95, 247, 715, 271 |
| 13 | 184, 19, 247, 143, 271 |
| 19 | 184, 19, 19, 11, 271 |
| 184, 1, 1, 11, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 19 x 184 x 1 x 1 x 11 x 271 = 2032207320
Therefore, the lowest common multiple of 920,285,247,715,813 is 2032207320.
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.
920 x 285 x 247 x 715 x 813 = 37646640603000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
285 : 1, 3, 5, 15, 19, 57, 95, 285
247 : 1, 13, 19, 247
715 : 1, 5, 11, 13, 55, 65, 143, 715
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,285,247,715,813, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
285:3x 5x 19
247:13x 19
715:5x 11x 13
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 13x 19 = 18525
Therefore, the value for common factors is 18525.
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 = 37646640603000/(1x18525)
LCM = 37646640603000/18525
LCM = 2032207320
Thus, we can understand that the LCM of 920,285,247,715,813 is 2032207320.
