Find LCM of 128,892,963,861,144 with Prime Factorization
| 2 | 128, 892, 963, 861, 144 |
| 2 | 64, 446, 963, 861, 72 |
| 2 | 32, 223, 963, 861, 36 |
| 2 | 16, 223, 963, 861, 18 |
| 3 | 8, 223, 963, 861, 9 |
| 3 | 8, 223, 321, 287, 3 |
| 8, 223, 107, 287, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 8 x 223 x 107 x 287 x 1 = 7889019264
Therefore, the lowest common multiple of 128,892,963,861,144 is 7889019264.
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 892 x 963 x 861 x 144 = 13632225288192
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
892 : 1, 2, 4, 223, 446, 892
963 : 1, 3, 9, 107, 321, 963
861 : 1, 3, 7, 21, 41, 123, 287, 861
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,892,963,861,144, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
892:2x 2x 223
963:3x 3x 107
861:3x 7x 41
144:2x 2x 2x 2x 3x 3
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 3x 3x 3 = 1728
Therefore, the value for common factors is 1728.
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 = 13632225288192/(1x1728)
LCM = 13632225288192/1728
LCM = 7889019264
Thus, we can understand that the LCM of 128,892,963,861,144 is 7889019264.
