Given numbers are 858,546,121,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,546,121,862 is 28474446.
Find LCM of 858,546,121,862 with Prime Factorization
2 | 858, 546, 121, 862 |
3 | 429, 273, 121, 431 |
11 | 143, 91, 121, 431 |
13 | 13, 91, 11, 431 |
1, 7, 11, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 1 x 7 x 11 x 431 = 28474446
Therefore, the lowest common multiple of 858,546,121,862 is 28474446.
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 546 x 121 x 862 = 48862149336
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
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
121 : 1, 11, 121
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,546,121,862, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
546:2x 3x 7x 13
121:11x 11
862:2x 431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 11x 13 = 1716
Therefore, the value for common factors is 1716.
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 = 48862149336/(1x1716)
LCM = 48862149336/1716
LCM = 28474446
Thus, we can understand that the LCM of 858,546,121,862 is 28474446.
