Find LCM of 681,479,288,664,881 with Prime Factorization
| 2 | 681, 479, 288, 664, 881 |
| 2 | 681, 479, 144, 332, 881 |
| 2 | 681, 479, 72, 166, 881 |
| 3 | 681, 479, 36, 83, 881 |
| 227, 479, 12, 83, 881 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 227 x 479 x 12 x 83 x 881 = 2289854349792
Therefore, the lowest common multiple of 681,479,288,664,881 is 2289854349792.
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.
681 x 479 x 288 x 664 x 881 = 54956504395008
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.
681 : 1, 3, 227, 681
479 : 1, 479
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
664 : 1, 2, 4, 8, 83, 166, 332, 664
881 : 1, 881
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,479,288,664,881, is 1.
Now, the common factors can be found like this.
681:3x 227
479:479
288:2x 2x 2x 2x 2x 3x 3
664:2x 2x 2x 83
881:881
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 3 = 24
Therefore, the value for common factors is 24.
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 = 54956504395008/(1x24)
LCM = 54956504395008/24
LCM = 2289854349792
Thus, we can understand that the LCM of 681,479,288,664,881 is 2289854349792.
