Find LCM of 868,792,357,942,778 with Prime Factorization
| 2 | 868, 792, 357, 942, 778 |
| 2 | 434, 396, 357, 471, 389 |
| 3 | 217, 198, 357, 471, 389 |
| 7 | 217, 66, 119, 157, 389 |
| 31, 66, 17, 157, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 66 x 17 x 157 x 389 = 178436251224
Therefore, the lowest common multiple of 868,792,357,942,778 is 178436251224.
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.
868 x 792 x 357 x 942 x 778 = 179863741233792
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
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
357 : 1, 3, 7, 17, 21, 51, 119, 357
942 : 1, 2, 3, 6, 157, 314, 471, 942
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,792,357,942,778, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
792:2x 2x 2x 3x 3x 11
357:3x 7x 17
942:2x 3x 157
778:2x 389
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 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 179863741233792/(1x1008)
LCM = 179863741233792/1008
LCM = 178436251224
Thus, we can understand that the LCM of 868,792,357,942,778 is 178436251224.
