Find LCM of 198,987,671,623,183 with Prime Factorization
| 3 | 198, 987, 671, 623, 183 |
| 7 | 66, 329, 671, 623, 61 |
| 11 | 66, 47, 671, 89, 61 |
| 61 | 6, 47, 61, 89, 61 |
| 6, 47, 1, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 61 x 6 x 47 x 1 x 89 x 1 = 353655918
Therefore, the lowest common multiple of 198,987,671,623,183 is 353655918.
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.
198 x 987 x 671 x 623 x 183 = 14950096621614
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
987 : 1, 3, 7, 21, 47, 141, 329, 987
671 : 1, 11, 61, 671
623 : 1, 7, 89, 623
183 : 1, 3, 61, 183
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,987,671,623,183, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
987:3x 7x 47
671:11x 61
623:7x 89
183:3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 11x 61 = 42273
Therefore, the value for common factors is 42273.
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 = 14950096621614/(1x42273)
LCM = 14950096621614/42273
LCM = 353655918
Thus, we can understand that the LCM of 198,987,671,623,183 is 353655918.
