Find LCM of 808,897,688,299,640 with Prime Factorization
| 2 | 808, 897, 688, 299, 640 |
| 2 | 404, 897, 344, 299, 320 |
| 2 | 202, 897, 172, 299, 160 |
| 2 | 101, 897, 86, 299, 80 |
| 13 | 101, 897, 43, 299, 40 |
| 23 | 101, 69, 43, 23, 40 |
| 101, 3, 43, 1, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 23 x 101 x 3 x 43 x 1 x 40 = 2493229440
Therefore, the lowest common multiple of 808,897,688,299,640 is 2493229440.
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.
808 x 897 x 688 x 299 x 640 = 95420877127680
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
897 : 1, 3, 13, 23, 39, 69, 299, 897
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
299 : 1, 13, 23, 299
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,897,688,299,640, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
897:3x 13x 23
688:2x 2x 2x 2x 43
299:13x 23
640:2x 2x 2x 2x 2x 2x 2x 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 2x 13x 23 = 38272
Therefore, the value for common factors is 38272.
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 = 95420877127680/(1x38272)
LCM = 95420877127680/38272
LCM = 2493229440
Thus, we can understand that the LCM of 808,897,688,299,640 is 2493229440.
