Given numbers are 818,921,630,678,975
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,921,630,678,975 is 581023948050.
Find LCM of 818,921,630,678,975 with Prime Factorization
| 2 | 818, 921, 630, 678, 975 |
| 3 | 409, 921, 315, 339, 975 |
| 5 | 409, 307, 105, 113, 325 |
| 409, 307, 21, 113, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 409 x 307 x 21 x 113 x 65 = 581023948050
Therefore, the lowest common multiple of 818,921,630,678,975 is 581023948050.
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.
818 x 921 x 630 x 678 x 975 = 313752931947000
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.
818 : 1, 2, 409, 818
921 : 1, 3, 307, 921
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
678 : 1, 2, 3, 6, 113, 226, 339, 678
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,921,630,678,975, is 1.
Now, the common factors can be found like this.
818:2x 409
921:3x 307
630:2x 3x 3x 5x 7
678:2x 3x 113
975:3x 5x 5x 13
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 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 313752931947000/(1x540)
LCM = 313752931947000/540
LCM = 581023948050
Thus, we can understand that the LCM of 818,921,630,678,975 is 581023948050.
