Given numbers are 172,903,690,653,256
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,903,690,653,256 is 17359560960.
Find LCM of 172,903,690,653,256 with Prime Factorization
| 2 | 172, 903, 690, 653, 256 |
| 2 | 86, 903, 345, 653, 128 |
| 3 | 43, 903, 345, 653, 64 |
| 43 | 43, 301, 115, 653, 64 |
| 1, 7, 115, 653, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 1 x 7 x 115 x 653 x 64 = 17359560960
Therefore, the lowest common multiple of 172,903,690,653,256 is 17359560960.
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.
172 x 903 x 690 x 653 x 256 = 17915066910720
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.
172 : 1, 2, 4, 43, 86, 172
903 : 1, 3, 7, 21, 43, 129, 301, 903
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
653 : 1, 653
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,903,690,653,256, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
903:3x 7x 43
690:2x 3x 5x 23
653:653
256:2x 2x 2x 2x 2x 2x 2x 2
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 3x 43 = 1032
Therefore, the value for common factors is 1032.
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 = 17915066910720/(1x1032)
LCM = 17915066910720/1032
LCM = 17359560960
Thus, we can understand that the LCM of 172,903,690,653,256 is 17359560960.
