Given numbers are 711,571,395,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,571,395,915 is 123824205.
Find LCM of 711,571,395,915 with Prime Factorization
| 3 | 711, 571, 395, 915 |
| 5 | 237, 571, 395, 305 |
| 79 | 237, 571, 79, 61 |
| 3, 571, 1, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 79 x 3 x 571 x 1 x 61 = 123824205
Therefore, the lowest common multiple of 711,571,395,915 is 123824205.
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.
711 x 571 x 395 x 915 = 146731682925
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.
711 : 1, 3, 9, 79, 237, 711
571 : 1, 571
395 : 1, 5, 79, 395
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,571,395,915, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
571:571
395:5x 79
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 79 = 1185
Therefore, the value for common factors is 1185.
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 = 146731682925/(1x1185)
LCM = 146731682925/1185
LCM = 123824205
Thus, we can understand that the LCM of 711,571,395,915 is 123824205.
