Given numbers are 120,315,617,676,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,315,617,676,231 is 2890447560.
Find LCM of 120,315,617,676,231 with Prime Factorization
| 2 | 120, 315, 617, 676, 231 |
| 2 | 60, 315, 617, 338, 231 |
| 3 | 30, 315, 617, 169, 231 |
| 5 | 10, 105, 617, 169, 77 |
| 7 | 2, 21, 617, 169, 77 |
| 2, 3, 617, 169, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 2 x 3 x 617 x 169 x 11 = 2890447560
Therefore, the lowest common multiple of 120,315,617,676,231 is 2890447560.
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 315 x 617 x 676 x 231 = 3641963925600
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
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
617 : 1, 617
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,315,617,676,231, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
315:3x 3x 5x 7
617:617
676:2x 2x 13x 13
231:3x 7x 11
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 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 3641963925600/(1x1260)
LCM = 3641963925600/1260
LCM = 2890447560
Thus, we can understand that the LCM of 120,315,617,676,231 is 2890447560.
