Given numbers are 387,860,480,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,860,480,913 is 56532960.
Find LCM of 387,860,480,913 with Prime Factorization
| 2 | 387, 860, 480, 913 |
| 2 | 387, 430, 240, 913 |
| 3 | 387, 215, 120, 913 |
| 5 | 129, 215, 40, 913 |
| 43 | 129, 43, 8, 913 |
| 3, 1, 8, 913 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 3 x 1 x 8 x 913 = 56532960
Therefore, the lowest common multiple of 387,860,480,913 is 56532960.
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.
387 x 860 x 480 x 913 = 145855036800
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.
387 : 1, 3, 9, 43, 129, 387
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,860,480,913, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
860:2x 2x 5x 43
480:2x 2x 2x 2x 2x 3x 5
913:11x 83
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 5x 43 = 2580
Therefore, the value for common factors is 2580.
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 = 145855036800/(1x2580)
LCM = 145855036800/2580
LCM = 56532960
Thus, we can understand that the LCM of 387,860,480,913 is 56532960.
