Given numbers are 731,430,518,484,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,430,518,484,400 is 9163523600.
Find LCM of 731,430,518,484,400 with Prime Factorization
| 2 | 731, 430, 518, 484, 400 |
| 2 | 731, 215, 259, 242, 200 |
| 5 | 731, 215, 259, 121, 100 |
| 43 | 731, 43, 259, 121, 20 |
| 17, 1, 259, 121, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 17 x 1 x 259 x 121 x 20 = 9163523600
Therefore, the lowest common multiple of 731,430,518,484,400 is 9163523600.
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 430 x 518 x 484 x 400 = 31522521184000
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
430 : 1, 2, 5, 10, 43, 86, 215, 430
518 : 1, 2, 7, 14, 37, 74, 259, 518
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,430,518,484,400, is 1.
Now, the common factors can be found like this.
731:17x 43
430:2x 5x 43
518:2x 7x 37
484:2x 2x 11x 11
400:2x 2x 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 2x 2x 5x 43 = 3440
Therefore, the value for common factors is 3440.
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 = 31522521184000/(1x3440)
LCM = 31522521184000/3440
LCM = 9163523600
Thus, we can understand that the LCM of 731,430,518,484,400 is 9163523600.
