Given numbers are 130,907,756,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 130,907,756,990 is 490269780.
Find LCM of 130,907,756,990 with Prime Factorization
| 2 | 130, 907, 756, 990 |
| 3 | 65, 907, 378, 495 |
| 3 | 65, 907, 126, 165 |
| 5 | 65, 907, 42, 55 |
| 13, 907, 42, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 907 x 42 x 11 = 490269780
Therefore, the lowest common multiple of 130,907,756,990 is 490269780.
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.
130 x 907 x 756 x 990 = 88248560400
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
907 : 1, 907
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,907,756,990, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
907:907
756:2x 2x 3x 3x 3x 7
990:2x 3x 3x 5x 11
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 5 = 180
Therefore, the value for common factors is 180.
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 = 88248560400/(1x180)
LCM = 88248560400/180
LCM = 490269780
Thus, we can understand that the LCM of 130,907,756,990 is 490269780.
