Given numbers are 665,857,286,949,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,857,286,949,676 is 309360391340.
Find LCM of 665,857,286,949,676 with Prime Factorization
2 | 665, 857, 286, 949, 676 |
13 | 665, 857, 143, 949, 338 |
665, 857, 11, 73, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 665 x 857 x 11 x 73 x 26 = 309360391340
Therefore, the lowest common multiple of 665,857,286,949,676 is 309360391340.
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.
665 x 857 x 286 x 949 x 676 = 104563812272920
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
857 : 1, 857
286 : 1, 2, 11, 13, 22, 26, 143, 286
949 : 1, 13, 73, 949
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,857,286,949,676, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
857:857
286:2x 11x 13
949:13x 73
676:2x 2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 104563812272920/(1x338)
LCM = 104563812272920/338
LCM = 309360391340
Thus, we can understand that the LCM of 665,857,286,949,676 is 309360391340.
