Given numbers are 383,861,820,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 383,861,820,707 is 666121260.
Find LCM of 383,861,820,707 with Prime Factorization
| 7 | 383, 861, 820, 707 |
| 41 | 383, 123, 820, 101 |
| 383, 3, 20, 101 |
Multiply the prime numbers at the bottom and the left side.
7 x 41 x 383 x 3 x 20 x 101 = 666121260
Therefore, the lowest common multiple of 383,861,820,707 is 666121260.
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.
383 x 861 x 820 x 707 = 191176801620
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.
383 : 1, 383
861 : 1, 3, 7, 21, 41, 123, 287, 861
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 383,861,820,707, is 1.
Now, the common factors can be found like this.
383:383
861:3x 7x 41
820:2x 2x 5x 41
707:7x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 41 = 287
Therefore, the value for common factors is 287.
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 = 191176801620/(1x287)
LCM = 191176801620/287
LCM = 666121260
Thus, we can understand that the LCM of 383,861,820,707 is 666121260.
