Given numbers are 481,949,780,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,949,780,100 is 10533900.
Find LCM of 481,949,780,100 with Prime Factorization
| 2 | 481, 949, 780, 100 |
| 2 | 481, 949, 390, 50 |
| 5 | 481, 949, 195, 25 |
| 13 | 481, 949, 39, 5 |
| 37, 73, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 37 x 73 x 3 x 5 = 10533900
Therefore, the lowest common multiple of 481,949,780,100 is 10533900.
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.
481 x 949 x 780 x 100 = 35604582000
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.
481 : 1, 13, 37, 481
949 : 1, 13, 73, 949
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,949,780,100, is 1.
Now, the common factors can be found like this.
481:13x 37
949:13x 73
780:2x 2x 3x 5x 13
100:2x 2x 5x 5
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 13x 13 = 3380
Therefore, the value for common factors is 3380.
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 = 35604582000/(1x3380)
LCM = 35604582000/3380
LCM = 10533900
Thus, we can understand that the LCM of 481,949,780,100 is 10533900.
