Find LCM of 408,649,944,680 with Prime Factorization
| 2 | 408, 649, 944, 680 |
| 2 | 204, 649, 472, 340 |
| 2 | 102, 649, 236, 170 |
| 17 | 51, 649, 118, 85 |
| 59 | 3, 649, 118, 5 |
| 3, 11, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 59 x 3 x 11 x 2 x 5 = 2647920
Therefore, the lowest common multiple of 408,649,944,680 is 2647920.
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.
408 x 649 x 944 x 680 = 169975280640
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
649 : 1, 11, 59, 649
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,649,944,680, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
649:11x 59
944:2x 2x 2x 2x 59
680:2x 2x 2x 5x 17
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 2x 2x 17x 59 = 64192
Therefore, the value for common factors is 64192.
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 = 169975280640/(1x64192)
LCM = 169975280640/64192
LCM = 2647920
Thus, we can understand that the LCM of 408,649,944,680 is 2647920.
