Find LCM of 378,656,792,641,248 with Prime Factorization
2 | 378, 656, 792, 641, 248 |
2 | 189, 328, 396, 641, 124 |
2 | 189, 164, 198, 641, 62 |
3 | 189, 82, 99, 641, 31 |
3 | 63, 82, 33, 641, 31 |
21, 82, 11, 641, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 21 x 82 x 11 x 641 x 31 = 27100546704
Therefore, the lowest common multiple of 378,656,792,641,248 is 27100546704.
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.
378 x 656 x 792 x 641 x 248 = 31219829803008
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
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
641 : 1, 641
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,656,792,641,248, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
656:2x 2x 2x 2x 41
792:2x 2x 2x 3x 3x 11
641:641
248:2x 2x 2x 31
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 2x 3x 3 = 1152
Therefore, the value for common factors is 1152.
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 = 31219829803008/(1x1152)
LCM = 31219829803008/1152
LCM = 27100546704
Thus, we can understand that the LCM of 378,656,792,641,248 is 27100546704.
