Given numbers are 874,920,874,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,920,874,518 is 4527320.
Find LCM of 874,920,874,518 with Prime Factorization
| 2 | 874, 920, 874, 518 |
| 19 | 437, 460, 437, 259 |
| 23 | 23, 460, 23, 259 |
| 1, 20, 1, 259 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 1 x 20 x 1 x 259 = 4527320
Therefore, the lowest common multiple of 874,920,874,518 is 4527320.
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 920 x 874 x 518 = 364032746560
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
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
874 : 1, 2, 19, 23, 38, 46, 437, 874
518 : 1, 2, 7, 14, 37, 74, 259, 518
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,920,874,518, is 2.
Now, the common factors can be found like this.
874:2x 19x 23
920:2x 2x 2x 5x 23
874:2x 19x 23
518:2x 7x 37
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 19x 23x 23 = 40204
Therefore, the value for common factors is 40204.
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 = 364032746560/(2x40204)
LCM = 364032746560/80408
LCM = 4527320
Thus, we can understand that the LCM of 874,920,874,518 is 4527320.
