Given numbers are 939,290,203,718,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,290,203,718,642 is 73221708210.
Find LCM of 939,290,203,718,642 with Prime Factorization
| 2 | 939, 290, 203, 718, 642 |
| 3 | 939, 145, 203, 359, 321 |
| 29 | 313, 145, 203, 359, 107 |
| 313, 5, 7, 359, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 313 x 5 x 7 x 359 x 107 = 73221708210
Therefore, the lowest common multiple of 939,290,203,718,642 is 73221708210.
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.
939 x 290 x 203 x 718 x 642 = 25481154457080
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.
939 : 1, 3, 313, 939
290 : 1, 2, 5, 10, 29, 58, 145, 290
203 : 1, 7, 29, 203
718 : 1, 2, 359, 718
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,290,203,718,642, is 1.
Now, the common factors can be found like this.
939:3x 313
290:2x 5x 29
203:7x 29
718:2x 359
642:2x 3x 107
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 29 = 348
Therefore, the value for common factors is 348.
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 = 25481154457080/(1x348)
LCM = 25481154457080/348
LCM = 73221708210
Thus, we can understand that the LCM of 939,290,203,718,642 is 73221708210.
