Find LCM of 128,995,646,456,895 with Prime Factorization
| 2 | 128, 995, 646, 456, 895 |
| 2 | 64, 995, 323, 228, 895 |
| 2 | 32, 995, 323, 114, 895 |
| 5 | 16, 995, 323, 57, 895 |
| 19 | 16, 199, 323, 57, 179 |
| 16, 199, 17, 3, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 19 x 16 x 199 x 17 x 3 x 179 = 22090719360
Therefore, the lowest common multiple of 128,995,646,456,895 is 22090719360.
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.
128 x 995 x 646 x 456 x 895 = 33577893427200
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
995 : 1, 5, 199, 995
646 : 1, 2, 17, 19, 34, 38, 323, 646
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,995,646,456,895, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
995:5x 199
646:2x 17x 19
456:2x 2x 2x 3x 19
895:5x 179
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 5x 19 = 1520
Therefore, the value for common factors is 1520.
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 = 33577893427200/(1x1520)
LCM = 33577893427200/1520
LCM = 22090719360
Thus, we can understand that the LCM of 128,995,646,456,895 is 22090719360.
