The LCM of 865,985,864,304 is 2797368480.
Find LCM of 865,985,864,304 with Prime Factorization
| 2 | 865, 985, 864, 304 |
| 2 | 865, 985, 432, 152 |
| 2 | 865, 985, 216, 76 |
| 2 | 865, 985, 108, 38 |
| 5 | 865, 985, 54, 19 |
| 173, 197, 54, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 173 x 197 x 54 x 19 = 2797368480
Therefore, the lowest common multiple of 865,985,864,304 is 2797368480.
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.
865 x 985 x 864 x 304 = 223789478400
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.
865 : 1, 5, 173, 865
985 : 1, 5, 197, 985
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,985,864,304, is 1.
Now, the common factors can be found like this.
865:5x 173
985:5x 197
864:2x 2x 2x 2x 2x 3x 3x 3
304:2x 2x 2x 2x 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 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 223789478400/(1x80)
LCM = 223789478400/80
LCM = 2797368480
Thus, we can understand that the LCM of 865,985,864,304 is 2797368480.
