Find LCM of 986,438,918,203 with Prime Factorization
| 2 | 986, 438, 918, 203 |
| 3 | 493, 219, 459, 203 |
| 17 | 493, 73, 153, 203 |
| 29 | 29, 73, 9, 203 |
| 1, 73, 9, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 29 x 1 x 73 x 9 x 7 = 13603842
Therefore, the lowest common multiple of 986,438,918,203 is 13603842.
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.
986 x 438 x 918 x 203 = 80480329272
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
438 : 1, 2, 3, 6, 73, 146, 219, 438
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,438,918,203, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
438:2x 3x 73
918:2x 3x 3x 3x 17
203:7x 29
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 3x 17x 29 = 5916
Therefore, the value for common factors is 5916.
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 = 80480329272/(1x5916)
LCM = 80480329272/5916
LCM = 13603842
Thus, we can understand that the LCM of 986,438,918,203 is 13603842.
