Given numbers are 858,820,431,955,368
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,820,431,955,368 is 2664217086960.
Find LCM of 858,820,431,955,368 with Prime Factorization
| 2 | 858, 820, 431, 955, 368 |
| 2 | 429, 410, 431, 955, 184 |
| 5 | 429, 205, 431, 955, 92 |
| 429, 41, 431, 191, 92 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 429 x 41 x 431 x 191 x 92 = 2664217086960
Therefore, the lowest common multiple of 858,820,431,955,368 is 2664217086960.
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 820 x 431 x 955 x 368 = 106568683478400
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
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
431 : 1, 431
955 : 1, 5, 191, 955
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,820,431,955,368, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
820:2x 2x 5x 41
431:431
955:5x 191
368:2x 2x 2x 2x 23
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 106568683478400/(1x40)
LCM = 106568683478400/40
LCM = 2664217086960
Thus, we can understand that the LCM of 858,820,431,955,368 is 2664217086960.
