Find LCM of 438,493,150,687,986 with Prime Factorization
| 2 | 438, 493, 150, 687, 986 |
| 3 | 219, 493, 75, 687, 493 |
| 17 | 73, 493, 25, 229, 493 |
| 29 | 73, 29, 25, 229, 29 |
| 73, 1, 25, 229, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 29 x 73 x 1 x 25 x 229 x 1 = 1236222150
Therefore, the lowest common multiple of 438,493,150,687,986 is 1236222150.
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.
438 x 493 x 150 x 687 x 986 = 21940470718200
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
493 : 1, 17, 29, 493
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
687 : 1, 3, 229, 687
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,493,150,687,986, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
493:17x 29
150:2x 3x 5x 5
687:3x 229
986:2x 17x 29
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 3x 3x 17x 29 = 17748
Therefore, the value for common factors is 17748.
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 = 21940470718200/(1x17748)
LCM = 21940470718200/17748
LCM = 1236222150
Thus, we can understand that the LCM of 438,493,150,687,986 is 1236222150.
