Find LCM of 216,138,774,397,104 with Prime Factorization
| 2 | 216, 138, 774, 397, 104 |
| 2 | 108, 69, 387, 397, 52 |
| 2 | 54, 69, 387, 397, 26 |
| 3 | 27, 69, 387, 397, 13 |
| 3 | 9, 23, 129, 397, 13 |
| 3, 23, 43, 397, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 23 x 43 x 397 x 13 = 1102513464
Therefore, the lowest common multiple of 216,138,774,397,104 is 1102513464.
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.
216 x 138 x 774 x 397 x 104 = 952571632896
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
138 : 1, 2, 3, 6, 23, 46, 69, 138
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
397 : 1, 397
104 : 1, 2, 4, 8, 13, 26, 52, 104
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,138,774,397,104, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
138:2x 3x 23
774:2x 3x 3x 43
397:397
104:2x 2x 2x 13
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 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 952571632896/(1x864)
LCM = 952571632896/864
LCM = 1102513464
Thus, we can understand that the LCM of 216,138,774,397,104 is 1102513464.
