Find LCM of 391,200,871,184,480 with Prime Factorization
| 2 | 391, 200, 871, 184, 480 |
| 2 | 391, 100, 871, 92, 240 |
| 2 | 391, 50, 871, 46, 120 |
| 5 | 391, 25, 871, 23, 60 |
| 23 | 391, 5, 871, 23, 12 |
| 17, 5, 871, 1, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 17 x 5 x 871 x 1 x 12 = 817346400
Therefore, the lowest common multiple of 391,200,871,184,480 is 817346400.
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.
391 x 200 x 871 x 184 x 480 = 6015669504000
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.
391 : 1, 17, 23, 391
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
871 : 1, 13, 67, 871
184 : 1, 2, 4, 8, 23, 46, 92, 184
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,200,871,184,480, is 1.
Now, the common factors can be found like this.
391:17x 23
200:2x 2x 2x 5x 5
871:13x 67
184:2x 2x 2x 23
480:2x 2x 2x 2x 2x 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 2x 2x 2x 2x 5x 23 = 7360
Therefore, the value for common factors is 7360.
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 = 6015669504000/(1x7360)
LCM = 6015669504000/7360
LCM = 817346400
Thus, we can understand that the LCM of 391,200,871,184,480 is 817346400.
