Given numbers are 391,510,885,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,510,885,291 is 67130790.
Find LCM of 391,510,885,291 with Prime Factorization
3 | 391, 510, 885, 291 |
5 | 391, 170, 295, 97 |
17 | 391, 34, 59, 97 |
23, 2, 59, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 23 x 2 x 59 x 97 = 67130790
Therefore, the lowest common multiple of 391,510,885,291 is 67130790.
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.
391 x 510 x 885 x 291 = 51355054350
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.
391 : 1, 17, 23, 391
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
885 : 1, 3, 5, 15, 59, 177, 295, 885
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,510,885,291, is 1.
Now, the common factors can be found like this.
391:17x 23
510:2x 3x 5x 17
885:3x 5x 59
291:3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 17 = 765
Therefore, the value for common factors is 765.
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 = 51355054350/(1x765)
LCM = 51355054350/765
LCM = 67130790
Thus, we can understand that the LCM of 391,510,885,291 is 67130790.
