Find LCM of 329,521,288,128,781 with Prime Factorization
| 2 | 329, 521, 288, 128, 781 |
| 2 | 329, 521, 144, 64, 781 |
| 2 | 329, 521, 72, 32, 781 |
| 2 | 329, 521, 36, 16, 781 |
| 2 | 329, 521, 18, 8, 781 |
| 329, 521, 9, 4, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 329 x 521 x 9 x 4 x 781 = 154218734208
Therefore, the lowest common multiple of 329,521,288,128,781 is 154218734208.
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.
329 x 521 x 288 x 128 x 781 = 4934999494656
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.
329 : 1, 7, 47, 329
521 : 1, 521
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
128 : 1, 2, 4, 8, 16, 32, 64, 128
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 329,521,288,128,781, is 1.
Now, the common factors can be found like this.
329:7x 47
521:521
288:2x 2x 2x 2x 2x 3x 3
128:2x 2x 2x 2x 2x 2x 2
781:11x 71
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 2 = 32
Therefore, the value for common factors is 32.
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 = 4934999494656/(1x32)
LCM = 4934999494656/32
LCM = 154218734208
Thus, we can understand that the LCM of 329,521,288,128,781 is 154218734208.
