Given numbers are 574,988,642,855,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 574,988,642,855,374 is 255315240180.
Find LCM of 574,988,642,855,374 with Prime Factorization
| 2 | 574, 988, 642, 855, 374 |
| 3 | 287, 494, 321, 855, 187 |
| 19 | 287, 494, 107, 285, 187 |
| 287, 26, 107, 15, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 287 x 26 x 107 x 15 x 187 = 255315240180
Therefore, the lowest common multiple of 574,988,642,855,374 is 255315240180.
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.
574 x 988 x 642 x 855 x 374 = 116423749522080
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.
574 : 1, 2, 7, 14, 41, 82, 287, 574
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
642 : 1, 2, 3, 6, 107, 214, 321, 642
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 574,988,642,855,374, is 1.
Now, the common factors can be found like this.
574:2x 7x 41
988:2x 2x 13x 19
642:2x 3x 107
855:3x 3x 5x 19
374:2x 11x 17
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 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 116423749522080/(1x456)
LCM = 116423749522080/456
LCM = 255315240180
Thus, we can understand that the LCM of 574,988,642,855,374 is 255315240180.
