Find LCM of 985,108,918,272 with Prime Factorization
| 2 | 985, 108, 918, 272 |
| 2 | 985, 54, 459, 136 |
| 3 | 985, 27, 459, 68 |
| 3 | 985, 9, 153, 68 |
| 3 | 985, 3, 51, 68 |
| 17 | 985, 1, 17, 68 |
| 985, 1, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 17 x 985 x 1 x 1 x 4 = 7233840
Therefore, the lowest common multiple of 985,108,918,272 is 7233840.
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.
985 x 108 x 918 x 272 = 26562660480
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.
985 : 1, 5, 197, 985
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,108,918,272, is 1.
Now, the common factors can be found like this.
985:5x 197
108:2x 2x 3x 3x 3
918:2x 3x 3x 3x 17
272:2x 2x 2x 2x 17
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 3x 3x 3x 17 = 3672
Therefore, the value for common factors is 3672.
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 = 26562660480/(1x3672)
LCM = 26562660480/3672
LCM = 7233840
Thus, we can understand that the LCM of 985,108,918,272 is 7233840.
