Given numbers are 874,445,571,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,445,571,805 is 1554553210.
Find LCM of 874,445,571,805 with Prime Factorization
| 5 | 874, 445, 571, 805 |
| 23 | 874, 89, 571, 161 |
| 38, 89, 571, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 38 x 89 x 571 x 7 = 1554553210
Therefore, the lowest common multiple of 874,445,571,805 is 1554553210.
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 445 x 571 x 805 = 178773619150
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
445 : 1, 5, 89, 445
571 : 1, 571
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,445,571,805, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
445:5x 89
571:571
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 178773619150/(1x115)
LCM = 178773619150/115
LCM = 1554553210
Thus, we can understand that the LCM of 874,445,571,805 is 1554553210.
