Given numbers are 942,858,970,396
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,858,970,396 is 391994460.
Find LCM of 942,858,970,396 with Prime Factorization
| 2 | 942, 858, 970, 396 |
| 3 | 471, 429, 485, 198 |
| 11 | 157, 143, 485, 66 |
| 157, 13, 485, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 157 x 13 x 485 x 6 = 391994460
Therefore, the lowest common multiple of 942,858,970,396 is 391994460.
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.
942 x 858 x 970 x 396 = 310459612320
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
970 : 1, 2, 5, 10, 97, 194, 485, 970
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,858,970,396, is 2.
Now, the common factors can be found like this.
942:2x 3x 157
858:2x 3x 11x 13
970:2x 5x 97
396:2x 2x 3x 3x 11
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 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 310459612320/(2x396)
LCM = 310459612320/792
LCM = 391994460
Thus, we can understand that the LCM of 942,858,970,396 is 391994460.
