The LCM of 398,985,766,130,591 is 5855752110.
Find LCM of 398,985,766,130,591 with Prime Factorization
| 2 | 398, 985, 766, 130, 591 |
| 5 | 199, 985, 383, 65, 591 |
| 197 | 199, 197, 383, 13, 591 |
| 199, 1, 383, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 197 x 199 x 1 x 383 x 13 x 3 = 5855752110
Therefore, the lowest common multiple of 398,985,766,130,591 is 5855752110.
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 985 x 766 x 130 x 591 = 23071663313400
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
985 : 1, 5, 197, 985
766 : 1, 2, 383, 766
130 : 1, 2, 5, 10, 13, 26, 65, 130
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,985,766,130,591, is 1.
Now, the common factors can be found like this.
398:2x 199
985:5x 197
766:2x 383
130:2x 5x 13
591:3x 197
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 5x 197 = 3940
Therefore, the value for common factors is 3940.
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 = 23071663313400/(1x3940)
LCM = 23071663313400/3940
LCM = 5855752110
Thus, we can understand that the LCM of 398,985,766,130,591 is 5855752110.
