Find LCM of 216,832,402,981 with Prime Factorization
| 2 | 216, 832, 402, 981 |
| 2 | 108, 416, 201, 981 |
| 2 | 54, 208, 201, 981 |
| 3 | 27, 104, 201, 981 |
| 3 | 9, 104, 67, 327 |
| 3, 104, 67, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 104 x 67 x 109 = 164054592
Therefore, the lowest common multiple of 216,832,402,981 is 164054592.
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 832 x 402 x 981 = 70871583744
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
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
402 : 1, 2, 3, 6, 67, 134, 201, 402
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,832,402,981, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
832:2x 2x 2x 2x 2x 2x 13
402:2x 3x 67
981:3x 3x 109
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 70871583744/(1x432)
LCM = 70871583744/432
LCM = 164054592
Thus, we can understand that the LCM of 216,832,402,981 is 164054592.
