Given numbers are 381,841,595,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,841,595,986 is 381300990.
Find LCM of 381,841,595,986 with Prime Factorization
| 17 | 381, 841, 595, 986 |
| 29 | 381, 841, 35, 58 |
| 381, 29, 35, 2 |
Multiply the prime numbers at the bottom and the left side.
17 x 29 x 381 x 29 x 35 x 2 = 381300990
Therefore, the lowest common multiple of 381,841,595,986 is 381300990.
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.
381 x 841 x 595 x 986 = 187981388070
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.
381 : 1, 3, 127, 381
841 : 1, 29, 841
595 : 1, 5, 7, 17, 35, 85, 119, 595
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,841,595,986, is 1.
Now, the common factors can be found like this.
381:3x 127
841:29x 29
595:5x 7x 17
986:2x 17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 29 = 493
Therefore, the value for common factors is 493.
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 = 187981388070/(1x493)
LCM = 187981388070/493
LCM = 381300990
Thus, we can understand that the LCM of 381,841,595,986 is 381300990.
