Find LCM of 638,319,893,510,860 with Prime Factorization
| 2 | 638, 319, 893, 510, 860 |
| 5 | 319, 319, 893, 255, 430 |
| 11 | 319, 319, 893, 51, 86 |
| 29 | 29, 29, 893, 51, 86 |
| 1, 1, 893, 51, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 29 x 1 x 1 x 893 x 51 x 86 = 12494266620
Therefore, the lowest common multiple of 638,319,893,510,860 is 12494266620.
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.
638 x 319 x 893 x 510 x 860 = 79713421035600
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
319 : 1, 11, 29, 319
893 : 1, 19, 47, 893
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,319,893,510,860, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
319:11x 29
893:19x 47
510:2x 3x 5x 17
860:2x 2x 5x 43
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 5x 11x 29 = 6380
Therefore, the value for common factors is 6380.
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 = 79713421035600/(1x6380)
LCM = 79713421035600/6380
LCM = 12494266620
Thus, we can understand that the LCM of 638,319,893,510,860 is 12494266620.
