Find LCM of 214,990,684,340 with Prime Factorization
2 | 214, 990, 684, 340 |
2 | 107, 495, 342, 170 |
3 | 107, 495, 171, 85 |
3 | 107, 165, 57, 85 |
5 | 107, 55, 19, 85 |
107, 11, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 107 x 11 x 19 x 17 = 68430780
Therefore, the lowest common multiple of 214,990,684,340 is 68430780.
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.
214 x 990 x 684 x 340 = 49270161600
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.
214 : 1, 2, 107, 214
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,990,684,340, is 2.
Now, the common factors can be found like this.
214:2x 107
990:2x 3x 3x 5x 11
684:2x 2x 3x 3x 19
340:2x 2x 5x 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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 49270161600/(2x360)
LCM = 49270161600/720
LCM = 68430780
Thus, we can understand that the LCM of 214,990,684,340 is 68430780.
