The LCM of 996,785,471,972 is 63330660.
Find LCM of 996,785,471,972 with Prime Factorization
| 2 | 996, 785, 471, 972 |
| 2 | 498, 785, 471, 486 |
| 3 | 249, 785, 471, 243 |
| 157 | 83, 785, 157, 81 |
| 83, 5, 1, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 157 x 83 x 5 x 1 x 81 = 63330660
Therefore, the lowest common multiple of 996,785,471,972 is 63330660.
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.
996 x 785 x 471 x 972 = 357944890320
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.
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
785 : 1, 5, 157, 785
471 : 1, 3, 157, 471
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 996,785,471,972, is 1.
Now, the common factors can be found like this.
996:2x 2x 3x 83
785:5x 157
471:3x 157
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 157 = 5652
Therefore, the value for common factors is 5652.
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 = 357944890320/(1x5652)
LCM = 357944890320/5652
LCM = 63330660
Thus, we can understand that the LCM of 996,785,471,972 is 63330660.
