Given numbers are 726,805,986,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 726,805,986,945 is 2593115910.
Find LCM of 726,805,986,945 with Prime Factorization
| 2 | 726, 805, 986, 945 |
| 3 | 363, 805, 493, 945 |
| 5 | 121, 805, 493, 315 |
| 7 | 121, 161, 493, 63 |
| 121, 23, 493, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 121 x 23 x 493 x 9 = 2593115910
Therefore, the lowest common multiple of 726,805,986,945 is 2593115910.
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.
726 x 805 x 986 x 945 = 544554341100
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
805 : 1, 5, 7, 23, 35, 115, 161, 805
986 : 1, 2, 17, 29, 34, 58, 493, 986
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,805,986,945, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
805:5x 7x 23
986:2x 17x 29
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 544554341100/(1x210)
LCM = 544554341100/210
LCM = 2593115910
Thus, we can understand that the LCM of 726,805,986,945 is 2593115910.
