Given numbers are 120,979,231,250,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,979,231,250,641 is 13178319000.
Find LCM of 120,979,231,250,641 with Prime Factorization
| 2 | 120, 979, 231, 250, 641 |
| 3 | 60, 979, 231, 125, 641 |
| 5 | 20, 979, 77, 125, 641 |
| 11 | 4, 979, 77, 25, 641 |
| 4, 89, 7, 25, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 4 x 89 x 7 x 25 x 641 = 13178319000
Therefore, the lowest common multiple of 120,979,231,250,641 is 13178319000.
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.
120 x 979 x 231 x 250 x 641 = 4348845270000
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
979 : 1, 11, 89, 979
231 : 1, 3, 7, 11, 21, 33, 77, 231
250 : 1, 2, 5, 10, 25, 50, 125, 250
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,979,231,250,641, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
979:11x 89
231:3x 7x 11
250:2x 5x 5x 5
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 4348845270000/(1x330)
LCM = 4348845270000/330
LCM = 13178319000
Thus, we can understand that the LCM of 120,979,231,250,641 is 13178319000.
