Given numbers are 858,154,857,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,154,857,901 is 4637574942.
Find LCM of 858,154,857,901 with Prime Factorization
2 | 858, 154, 857, 901 |
11 | 429, 77, 857, 901 |
39, 7, 857, 901 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 39 x 7 x 857 x 901 = 4637574942
Therefore, the lowest common multiple of 858,154,857,901 is 4637574942.
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.
858 x 154 x 857 x 901 = 102026648724
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
154 : 1, 2, 7, 11, 14, 22, 77, 154
857 : 1, 857
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,154,857,901, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
154:2x 7x 11
857:857
901:17x 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 11 = 22
Therefore, the value for common factors is 22.
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 = 102026648724/(1x22)
LCM = 102026648724/22
LCM = 4637574942
Thus, we can understand that the LCM of 858,154,857,901 is 4637574942.
