Find LCM of 248,816,917,363,390 with Prime Factorization
| 2 | 248, 816, 917, 363, 390 |
| 2 | 124, 408, 917, 363, 195 |
| 2 | 62, 204, 917, 363, 195 |
| 3 | 31, 102, 917, 363, 195 |
| 31, 34, 917, 121, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 31 x 34 x 917 x 121 x 65 = 182439937680
Therefore, the lowest common multiple of 248,816,917,363,390 is 182439937680.
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.
248 x 816 x 917 x 363 x 390 = 26271351025920
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
917 : 1, 7, 131, 917
363 : 1, 3, 11, 33, 121, 363
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,816,917,363,390, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
816:2x 2x 2x 2x 3x 17
917:7x 131
363:3x 11x 11
390:2x 3x 5x 13
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 26271351025920/(1x144)
LCM = 26271351025920/144
LCM = 182439937680
Thus, we can understand that the LCM of 248,816,917,363,390 is 182439937680.
