The LCM of 836,665,752,388 is 533585360.
Find LCM of 836,665,752,388 with Prime Factorization
| 2 | 836, 665, 752, 388 |
| 2 | 418, 665, 376, 194 |
| 19 | 209, 665, 188, 97 |
| 11, 35, 188, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 11 x 35 x 188 x 97 = 533585360
Therefore, the lowest common multiple of 836,665,752,388 is 533585360.
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.
836 x 665 x 752 x 388 = 162209949440
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
665 : 1, 5, 7, 19, 35, 95, 133, 665
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,665,752,388, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
665:5x 7x 19
752:2x 2x 2x 2x 47
388:2x 2x 97
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 19 = 304
Therefore, the value for common factors is 304.
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 = 162209949440/(1x304)
LCM = 162209949440/304
LCM = 533585360
Thus, we can understand that the LCM of 836,665,752,388 is 533585360.
