Find LCM of 314,690,285,418 with Prime Factorization
| 2 | 314, 690, 285, 418 |
| 3 | 157, 345, 285, 209 |
| 5 | 157, 115, 95, 209 |
| 19 | 157, 23, 19, 209 |
| 157, 23, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 157 x 23 x 1 x 11 = 22640970
Therefore, the lowest common multiple of 314,690,285,418 is 22640970.
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.
314 x 690 x 285 x 418 = 25810705800
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.
314 : 1, 2, 157, 314
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
285 : 1, 3, 5, 15, 19, 57, 95, 285
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 314,690,285,418, is 1.
Now, the common factors can be found like this.
314:2x 157
690:2x 3x 5x 23
285:3x 5x 19
418:2x 11x 19
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 5x 19 = 1140
Therefore, the value for common factors is 1140.
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 = 25810705800/(1x1140)
LCM = 25810705800/1140
LCM = 22640970
Thus, we can understand that the LCM of 314,690,285,418 is 22640970.
