Find LCM of 649,779,935,736,128 with Prime Factorization
| 2 | 649, 779, 935, 736, 128 |
| 2 | 649, 779, 935, 368, 64 |
| 2 | 649, 779, 935, 184, 32 |
| 2 | 649, 779, 935, 92, 16 |
| 2 | 649, 779, 935, 46, 8 |
| 11 | 649, 779, 935, 23, 4 |
| 59, 779, 85, 23, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 11 x 59 x 779 x 85 x 23 x 4 = 126514087040
Therefore, the lowest common multiple of 649,779,935,736,128 is 126514087040.
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.
649 x 779 x 935 x 736 x 128 = 44532958638080
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.
649 : 1, 11, 59, 649
779 : 1, 19, 41, 779
935 : 1, 5, 11, 17, 55, 85, 187, 935
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,779,935,736,128, is 1.
Now, the common factors can be found like this.
649:11x 59
779:19x 41
935:5x 11x 17
736:2x 2x 2x 2x 2x 23
128:2x 2x 2x 2x 2x 2x 2
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 11 = 352
Therefore, the value for common factors is 352.
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 = 44532958638080/(1x352)
LCM = 44532958638080/352
LCM = 126514087040
Thus, we can understand that the LCM of 649,779,935,736,128 is 126514087040.
