The LCM of 556,792,781,999 is 867603528.
Find LCM of 556,792,781,999 with Prime Factorization
| 2 | 556, 792, 781, 999 |
| 2 | 278, 396, 781, 999 |
| 3 | 139, 198, 781, 999 |
| 3 | 139, 66, 781, 333 |
| 11 | 139, 22, 781, 111 |
| 139, 2, 71, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 139 x 2 x 71 x 111 = 867603528
Therefore, the lowest common multiple of 556,792,781,999 is 867603528.
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.
556 x 792 x 781 x 999 = 343570997088
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.
556 : 1, 2, 4, 139, 278, 556
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
781 : 1, 11, 71, 781
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,792,781,999, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
792:2x 2x 2x 3x 3x 11
781:11x 71
999:3x 3x 3x 37
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 11 = 396
Therefore, the value for common factors is 396.
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 = 343570997088/(1x396)
LCM = 343570997088/396
LCM = 867603528
Thus, we can understand that the LCM of 556,792,781,999 is 867603528.
