Given numbers are 808,858,221,907,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,858,221,907,988 is 101549657352.
Find LCM of 808,858,221,907,988 with Prime Factorization
| 2 | 808, 858, 221, 907, 988 |
| 2 | 404, 429, 221, 907, 494 |
| 13 | 202, 429, 221, 907, 247 |
| 202, 33, 17, 907, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 202 x 33 x 17 x 907 x 19 = 101549657352
Therefore, the lowest common multiple of 808,858,221,907,988 is 101549657352.
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 858 x 221 x 907 x 988 = 137295136739904
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
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
221 : 1, 13, 17, 221
907 : 1, 907
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,858,221,907,988, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
858:2x 3x 11x 13
221:13x 17
907:907
988:2x 2x 13x 19
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 13x 13 = 1352
Therefore, the value for common factors is 1352.
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 = 137295136739904/(1x1352)
LCM = 137295136739904/1352
LCM = 101549657352
Thus, we can understand that the LCM of 808,858,221,907,988 is 101549657352.
