Given numbers are 391,345,913,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,345,913,291 is 519410265.
Find LCM of 391,345,913,291 with Prime Factorization
| 3 | 391, 345, 913, 291 |
| 23 | 391, 115, 913, 97 |
| 17, 5, 913, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 17 x 5 x 913 x 97 = 519410265
Therefore, the lowest common multiple of 391,345,913,291 is 519410265.
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 345 x 913 x 291 = 35839308285
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
345 : 1, 3, 5, 15, 23, 69, 115, 345
913 : 1, 11, 83, 913
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,345,913,291, is 1.
Now, the common factors can be found like this.
391:17x 23
345:3x 5x 23
913:11x 83
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 23 = 69
Therefore, the value for common factors is 69.
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 = 35839308285/(1x69)
LCM = 35839308285/69
LCM = 519410265
Thus, we can understand that the LCM of 391,345,913,291 is 519410265.
