Given numbers are 971,715,858,424
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 971,715,858,424 is 883105080.
Find LCM of 971,715,858,424 with Prime Factorization
| 2 | 971, 715, 858, 424 |
| 11 | 971, 715, 429, 212 |
| 13 | 971, 65, 39, 212 |
| 971, 5, 3, 212 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 971 x 5 x 3 x 212 = 883105080
Therefore, the lowest common multiple of 971,715,858,424 is 883105080.
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.
971 x 715 x 858 x 424 = 252568052880
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.
971 : 1, 971
715 : 1, 5, 11, 13, 55, 65, 143, 715
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,715,858,424, is 1.
Now, the common factors can be found like this.
971:971
715:5x 11x 13
858:2x 3x 11x 13
424:2x 2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 252568052880/(1x286)
LCM = 252568052880/286
LCM = 883105080
Thus, we can understand that the LCM of 971,715,858,424 is 883105080.
