Given numbers are 493,352,731,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,352,731,220 is 37310240.
Find LCM of 493,352,731,220 with Prime Factorization
| 2 | 493, 352, 731, 220 |
| 2 | 493, 176, 731, 110 |
| 11 | 493, 88, 731, 55 |
| 17 | 493, 8, 731, 5 |
| 29, 8, 43, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 29 x 8 x 43 x 5 = 37310240
Therefore, the lowest common multiple of 493,352,731,220 is 37310240.
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.
493 x 352 x 731 x 220 = 27908059520
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.
493 : 1, 17, 29, 493
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
731 : 1, 17, 43, 731
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,352,731,220, is 1.
Now, the common factors can be found like this.
493:17x 29
352:2x 2x 2x 2x 2x 11
731:17x 43
220:2x 2x 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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 27908059520/(1x748)
LCM = 27908059520/748
LCM = 37310240
Thus, we can understand that the LCM of 493,352,731,220 is 37310240.
