Given numbers are 905,169,884,714,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,169,884,714,961 is 209887647060.
Find LCM of 905,169,884,714,961 with Prime Factorization
| 2 | 905, 169, 884, 714, 961 |
| 13 | 905, 169, 442, 357, 961 |
| 17 | 905, 13, 34, 357, 961 |
| 905, 13, 2, 21, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 905 x 13 x 2 x 21 x 961 = 209887647060
Therefore, the lowest common multiple of 905,169,884,714,961 is 209887647060.
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.
905 x 169 x 884 x 714 x 961 = 92770340000520
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.
905 : 1, 5, 181, 905
169 : 1, 13, 169
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,169,884,714,961, is 1.
Now, the common factors can be found like this.
905:5x 181
169:13x 13
884:2x 2x 13x 17
714:2x 3x 7x 17
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 92770340000520/(1x442)
LCM = 92770340000520/442
LCM = 209887647060
Thus, we can understand that the LCM of 905,169,884,714,961 is 209887647060.
