Given numbers are 380,494,891,782,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,494,891,782,964 is 414761515740.
Find LCM of 380,494,891,782,964 with Prime Factorization
| 2 | 380, 494, 891, 782, 964 |
| 2 | 190, 247, 891, 391, 482 |
| 19 | 95, 247, 891, 391, 241 |
| 5, 13, 891, 391, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 5 x 13 x 891 x 391 x 241 = 414761515740
Therefore, the lowest common multiple of 380,494,891,782,964 is 414761515740.
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.
380 x 494 x 891 x 782 x 964 = 126087500784960
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
494 : 1, 2, 13, 19, 26, 38, 247, 494
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
782 : 1, 2, 17, 23, 34, 46, 391, 782
964 : 1, 2, 4, 241, 482, 964
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,494,891,782,964, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
494:2x 13x 19
891:3x 3x 3x 3x 11
782:2x 17x 23
964:2x 2x 241
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 2x 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 126087500784960/(1x304)
LCM = 126087500784960/304
LCM = 414761515740
Thus, we can understand that the LCM of 380,494,891,782,964 is 414761515740.
