Given numbers are 874,842,554,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,842,554,418 is 1121155838.
Find LCM of 874,842,554,418 with Prime Factorization
| 2 | 874, 842, 554, 418 |
| 19 | 437, 421, 277, 209 |
| 23, 421, 277, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 421 x 277 x 11 = 1121155838
Therefore, the lowest common multiple of 874,842,554,418 is 1121155838.
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.
874 x 842 x 554 x 418 = 170415687376
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
842 : 1, 2, 421, 842
554 : 1, 2, 277, 554
418 : 1, 2, 11, 19, 22, 38, 209, 418
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,842,554,418, is 2.
Now, the common factors can be found like this.
874:2x 19x 23
842:2x 421
554:2x 277
418:2x 11x 19
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 19 = 76
Therefore, the value for common factors is 76.
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 = 170415687376/(2x76)
LCM = 170415687376/152
LCM = 1121155838
Thus, we can understand that the LCM of 874,842,554,418 is 1121155838.
