Given numbers are 386,985,920,946,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,985,920,946,869 is 1307072250440.
Find LCM of 386,985,920,946,869 with Prime Factorization
| 2 | 386, 985, 920, 946, 869 |
| 5 | 193, 985, 460, 473, 869 |
| 11 | 193, 197, 92, 473, 869 |
| 193, 197, 92, 43, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 193 x 197 x 92 x 43 x 79 = 1307072250440
Therefore, the lowest common multiple of 386,985,920,946,869 is 1307072250440.
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.
386 x 985 x 920 x 946 x 869 = 287555895096800
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.
386 : 1, 2, 193, 386
985 : 1, 5, 197, 985
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
946 : 1, 2, 11, 22, 43, 86, 473, 946
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,985,920,946,869, is 1.
Now, the common factors can be found like this.
386:2x 193
985:5x 197
920:2x 2x 2x 5x 23
946:2x 11x 43
869:11x 79
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 287555895096800/(1x220)
LCM = 287555895096800/220
LCM = 1307072250440
Thus, we can understand that the LCM of 386,985,920,946,869 is 1307072250440.
