Given numbers are 139,638,185,999,998
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,638,185,999,998 is 221040328410.
Find LCM of 139,638,185,999,998 with Prime Factorization
| 2 | 139, 638, 185, 999, 998 |
| 37 | 139, 319, 185, 999, 499 |
| 139, 319, 5, 27, 499 |
Multiply the prime numbers at the bottom and the left side.
2 x 37 x 139 x 319 x 5 x 27 x 499 = 221040328410
Therefore, the lowest common multiple of 139,638,185,999,998 is 221040328410.
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.
139 x 638 x 185 x 999 x 998 = 16356984302340
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.
139 : 1, 139
638 : 1, 2, 11, 22, 29, 58, 319, 638
185 : 1, 5, 37, 185
999 : 1, 3, 9, 27, 37, 111, 333, 999
998 : 1, 2, 499, 998
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,638,185,999,998, is 1.
Now, the common factors can be found like this.
139:139
638:2x 11x 29
185:5x 37
999:3x 3x 3x 37
998:2x 499
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 37 = 74
Therefore, the value for common factors is 74.
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 = 16356984302340/(1x74)
LCM = 16356984302340/74
LCM = 221040328410
Thus, we can understand that the LCM of 139,638,185,999,998 is 221040328410.
