Given numbers are 983,989,726,620,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 983,989,726,620,805 is 1531602843540.
Find LCM of 983,989,726,620,805 with Prime Factorization
| 2 | 983, 989, 726, 620, 805 |
| 5 | 983, 989, 363, 310, 805 |
| 23 | 983, 989, 363, 62, 161 |
| 983, 43, 363, 62, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 983 x 43 x 363 x 62 x 7 = 1531602843540
Therefore, the lowest common multiple of 983,989,726,620,805 is 1531602843540.
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.
983 x 989 x 726 x 620 x 805 = 352268654014200
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.
983 : 1, 983
989 : 1, 23, 43, 989
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,989,726,620,805, is 1.
Now, the common factors can be found like this.
983:983
989:23x 43
726:2x 3x 11x 11
620:2x 2x 5x 31
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 23 = 230
Therefore, the value for common factors is 230.
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 = 352268654014200/(1x230)
LCM = 352268654014200/230
LCM = 1531602843540
Thus, we can understand that the LCM of 983,989,726,620,805 is 1531602843540.
