The LCM of 372,308,561,872 is 106154664.
Find LCM of 372,308,561,872 with Prime Factorization
| 2 | 372, 308, 561, 872 |
| 2 | 186, 154, 561, 436 |
| 3 | 93, 77, 561, 218 |
| 11 | 31, 77, 187, 218 |
| 31, 7, 17, 218 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 31 x 7 x 17 x 218 = 106154664
Therefore, the lowest common multiple of 372,308,561,872 is 106154664.
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.
372 x 308 x 561 x 872 = 56049662592
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
561 : 1, 3, 11, 17, 33, 51, 187, 561
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,308,561,872, is 1.
Now, the common factors can be found like this.
372:2x 2x 3x 31
308:2x 2x 7x 11
561:3x 11x 17
872:2x 2x 2x 109
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 11 = 528
Therefore, the value for common factors is 528.
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 = 56049662592/(1x528)
LCM = 56049662592/528
LCM = 106154664
Thus, we can understand that the LCM of 372,308,561,872 is 106154664.
