The LCM of 215,762,889,128,178 is 6532229760.
Find LCM of 215,762,889,128,178 with Prime Factorization
| 2 | 215, 762, 889, 128, 178 |
| 127 | 215, 381, 889, 64, 89 |
| 215, 3, 7, 64, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 127 x 215 x 3 x 7 x 64 x 89 = 6532229760
Therefore, the lowest common multiple of 215,762,889,128,178 is 6532229760.
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.
215 x 762 x 889 x 128 x 178 = 3318372718080
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.
215 : 1, 5, 43, 215
762 : 1, 2, 3, 6, 127, 254, 381, 762
889 : 1, 7, 127, 889
128 : 1, 2, 4, 8, 16, 32, 64, 128
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,762,889,128,178, is 1.
Now, the common factors can be found like this.
215:5x 43
762:2x 3x 127
889:7x 127
128:2x 2x 2x 2x 2x 2x 2
178:2x 89
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 127 = 508
Therefore, the value for common factors is 508.
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 = 3318372718080/(1x508)
LCM = 3318372718080/508
LCM = 6532229760
Thus, we can understand that the LCM of 215,762,889,128,178 is 6532229760.
