Find LCM of 866,102,128,432,991 with Prime Factorization
| 2 | 866, 102, 128, 432, 991 |
| 2 | 433, 51, 64, 216, 991 |
| 2 | 433, 51, 32, 108, 991 |
| 2 | 433, 51, 16, 54, 991 |
| 3 | 433, 51, 8, 27, 991 |
| 433, 17, 8, 9, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 433 x 17 x 8 x 9 x 991 = 25210659456
Therefore, the lowest common multiple of 866,102,128,432,991 is 25210659456.
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.
866 x 102 x 128 x 432 x 991 = 4840446615552
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.
866 : 1, 2, 433, 866
102 : 1, 2, 3, 6, 17, 34, 51, 102
128 : 1, 2, 4, 8, 16, 32, 64, 128
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,102,128,432,991, is 1.
Now, the common factors can be found like this.
866:2x 433
102:2x 3x 17
128:2x 2x 2x 2x 2x 2x 2
432:2x 2x 2x 2x 3x 3x 3
991:991
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 3 = 192
Therefore, the value for common factors is 192.
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 = 4840446615552/(1x192)
LCM = 4840446615552/192
LCM = 25210659456
Thus, we can understand that the LCM of 866,102,128,432,991 is 25210659456.
