The LCM of 902,687,264,561 is 42137832.
Find LCM of 902,687,264,561 with Prime Factorization
| 2 | 902, 687, 264, 561 |
| 3 | 451, 687, 132, 561 |
| 11 | 451, 229, 44, 187 |
| 41, 229, 4, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 41 x 229 x 4 x 17 = 42137832
Therefore, the lowest common multiple of 902,687,264,561 is 42137832.
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.
902 x 687 x 264 x 561 = 91776198096
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
687 : 1, 3, 229, 687
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,687,264,561, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
687:3x 229
264:2x 2x 2x 3x 11
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11x 11 = 2178
Therefore, the value for common factors is 2178.
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 = 91776198096/(1x2178)
LCM = 91776198096/2178
LCM = 42137832
Thus, we can understand that the LCM of 902,687,264,561 is 42137832.
