Given numbers are 172,831,132,753,456
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,831,132,753,456 is 14996139576.
Find LCM of 172,831,132,753,456 with Prime Factorization
| 2 | 172, 831, 132, 753, 456 |
| 2 | 86, 831, 66, 753, 228 |
| 3 | 43, 831, 33, 753, 114 |
| 43, 277, 11, 251, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 277 x 11 x 251 x 38 = 14996139576
Therefore, the lowest common multiple of 172,831,132,753,456 is 14996139576.
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 831 x 132 x 753 x 456 = 6478332296832
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
831 : 1, 3, 277, 831
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
753 : 1, 3, 251, 753
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,831,132,753,456, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
831:3x 277
132:2x 2x 3x 11
753:3x 251
456:2x 2x 2x 3x 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 2x 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 6478332296832/(1x432)
LCM = 6478332296832/432
LCM = 14996139576
Thus, we can understand that the LCM of 172,831,132,753,456 is 14996139576.
