Given numbers are 317,947,471,876,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 317,947,471,876,620 is 6399480174540.
Find LCM of 317,947,471,876,620 with Prime Factorization
| 2 | 317, 947, 471, 876, 620 |
| 2 | 317, 947, 471, 438, 310 |
| 3 | 317, 947, 471, 219, 155 |
| 317, 947, 157, 73, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 317 x 947 x 157 x 73 x 155 = 6399480174540
Therefore, the lowest common multiple of 317,947,471,876,620 is 6399480174540.
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.
317 x 947 x 471 x 876 x 620 = 76793762094480
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.
317 : 1, 317
947 : 1, 947
471 : 1, 3, 157, 471
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,947,471,876,620, is 1.
Now, the common factors can be found like this.
317:317
947:947
471:3x 157
876:2x 2x 3x 73
620:2x 2x 5x 31
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 3 = 12
Therefore, the value for common factors is 12.
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 = 76793762094480/(1x12)
LCM = 76793762094480/12
LCM = 6399480174540
Thus, we can understand that the LCM of 317,947,471,876,620 is 6399480174540.
