Given numbers are 398,993,782,975,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,993,782,975,782 is 50221819050.
Find LCM of 398,993,782,975,782 with Prime Factorization
| 2 | 398, 993, 782, 975, 782 |
| 3 | 199, 993, 391, 975, 391 |
| 17 | 199, 331, 391, 325, 391 |
| 23 | 199, 331, 23, 325, 23 |
| 199, 331, 1, 325, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 23 x 199 x 331 x 1 x 325 x 1 = 50221819050
Therefore, the lowest common multiple of 398,993,782,975,782 is 50221819050.
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.
398 x 993 x 782 x 975 x 782 = 235640774982600
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.
398 : 1, 2, 199, 398
993 : 1, 3, 331, 993
782 : 1, 2, 17, 23, 34, 46, 391, 782
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,993,782,975,782, is 1.
Now, the common factors can be found like this.
398:2x 199
993:3x 331
782:2x 17x 23
975:3x 5x 5x 13
782:2x 17x 23
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 17x 23 = 4692
Therefore, the value for common factors is 4692.
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 = 235640774982600/(1x4692)
LCM = 235640774982600/4692
LCM = 50221819050
Thus, we can understand that the LCM of 398,993,782,975,782 is 50221819050.
