The LCM of 912,665,996,621 is 548417520.
Find LCM of 912,665,996,621 with Prime Factorization
| 2 | 912, 665, 996, 621 |
| 2 | 456, 665, 498, 621 |
| 3 | 228, 665, 249, 621 |
| 19 | 76, 665, 83, 207 |
| 4, 35, 83, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 4 x 35 x 83 x 207 = 548417520
Therefore, the lowest common multiple of 912,665,996,621 is 548417520.
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.
912 x 665 x 996 x 621 = 375117583680
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
665 : 1, 5, 7, 19, 35, 95, 133, 665
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,665,996,621, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
665:5x 7x 19
996:2x 2x 3x 83
621:3x 3x 3x 23
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 19 = 684
Therefore, the value for common factors is 684.
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 = 375117583680/(1x684)
LCM = 375117583680/684
LCM = 548417520
Thus, we can understand that the LCM of 912,665,996,621 is 548417520.
