Find LCM of 290,718,990,324,257 with Prime Factorization
| 2 | 290, 718, 990, 324, 257 |
| 3 | 145, 359, 495, 162, 257 |
| 3 | 145, 359, 165, 54, 257 |
| 5 | 145, 359, 55, 18, 257 |
| 29, 359, 11, 18, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 29 x 359 x 11 x 18 x 257 = 47679673140
Therefore, the lowest common multiple of 290,718,990,324,257 is 47679673140.
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.
290 x 718 x 990 x 324 x 257 = 17164682330400
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
718 : 1, 2, 359, 718
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
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,718,990,324,257, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
718:2x 359
990:2x 3x 3x 5x 11
324:2x 2x 3x 3x 3x 3
257:257
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 = 17164682330400/(1x360)
LCM = 17164682330400/360
LCM = 47679673140
Thus, we can understand that the LCM of 290,718,990,324,257 is 47679673140.
