Given numbers are 903,728,172,101
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 903,728,172,101 is 9485112.
Find LCM of 903,728,172,101 with Prime Factorization
| 2 | 903, 728, 172, 101 |
| 2 | 903, 364, 86, 101 |
| 7 | 903, 182, 43, 101 |
| 43 | 129, 26, 43, 101 |
| 3, 26, 1, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 43 x 3 x 26 x 1 x 101 = 9485112
Therefore, the lowest common multiple of 903,728,172,101 is 9485112.
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.
903 x 728 x 172 x 101 = 11420074848
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.
903 : 1, 3, 7, 21, 43, 129, 301, 903
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
172 : 1, 2, 4, 43, 86, 172
101 : 1, 101
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,728,172,101, is 1.
Now, the common factors can be found like this.
903:3x 7x 43
728:2x 2x 2x 7x 13
172:2x 2x 43
101:101
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 7x 43 = 1204
Therefore, the value for common factors is 1204.
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 = 11420074848/(1x1204)
LCM = 11420074848/1204
LCM = 9485112
Thus, we can understand that the LCM of 903,728,172,101 is 9485112.
