Given numbers are 300,935,387,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 300,935,387,781 is 513819900.
Find LCM of 300,935,387,781 with Prime Factorization
| 3 | 300, 935, 387, 781 |
| 5 | 100, 935, 129, 781 |
| 11 | 20, 187, 129, 781 |
| 20, 17, 129, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 20 x 17 x 129 x 71 = 513819900
Therefore, the lowest common multiple of 300,935,387,781 is 513819900.
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.
300 x 935 x 387 x 781 = 84780283500
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.
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
935 : 1, 5, 11, 17, 55, 85, 187, 935
387 : 1, 3, 9, 43, 129, 387
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 300,935,387,781, is 1.
Now, the common factors can be found like this.
300:2x 2x 3x 5x 5
935:5x 11x 17
387:3x 3x 43
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 84780283500/(1x165)
LCM = 84780283500/165
LCM = 513819900
Thus, we can understand that the LCM of 300,935,387,781 is 513819900.
