Find LCM of 162,442,574,840,238 with Prime Factorization
| 2 | 162, 442, 574, 840, 238 |
| 3 | 81, 221, 287, 420, 119 |
| 7 | 27, 221, 287, 140, 119 |
| 17 | 27, 221, 41, 20, 17 |
| 27, 13, 41, 20, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 27 x 13 x 41 x 20 x 1 = 205503480
Therefore, the lowest common multiple of 162,442,574,840,238 is 205503480.
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.
162 x 442 x 574 x 840 x 238 = 8216851144320
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
442 : 1, 2, 13, 17, 26, 34, 221, 442
574 : 1, 2, 7, 14, 41, 82, 287, 574
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
238 : 1, 2, 7, 14, 17, 34, 119, 238
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,442,574,840,238, is 2.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
442:2x 13x 17
574:2x 7x 41
840:2x 2x 2x 3x 5x 7
238:2x 7x 17
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 3x 7x 7x 17 = 19992
Therefore, the value for common factors is 19992.
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 = 8216851144320/(2x19992)
LCM = 8216851144320/39984
LCM = 205503480
Thus, we can understand that the LCM of 162,442,574,840,238 is 205503480.
