Given numbers are 731,833,945,983,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,833,945,983,688 is 76053766320.
Find LCM of 731,833,945,983,688 with Prime Factorization
| 7 | 731, 833, 945, 983, 688 |
| 17 | 731, 119, 135, 983, 688 |
| 43 | 43, 7, 135, 983, 688 |
| 1, 7, 135, 983, 16 |
Multiply the prime numbers at the bottom and the left side.
7 x 17 x 43 x 1 x 7 x 135 x 983 x 16 = 76053766320
Therefore, the lowest common multiple of 731,833,945,983,688 is 76053766320.
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.
731 x 833 x 945 x 983 x 688 = 389167122259440
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.
731 : 1, 17, 43, 731
833 : 1, 7, 17, 49, 119, 833
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
983 : 1, 983
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,833,945,983,688, is 1.
Now, the common factors can be found like this.
731:17x 43
833:7x 7x 17
945:3x 3x 3x 5x 7
983:983
688:2x 2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 17x 43 = 5117
Therefore, the value for common factors is 5117.
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 = 389167122259440/(1x5117)
LCM = 389167122259440/5117
LCM = 76053766320
Thus, we can understand that the LCM of 731,833,945,983,688 is 76053766320.
