The LCM of 838,944,440,121 is 239299280.
Find LCM of 838,944,440,121 with Prime Factorization
| 2 | 838, 944, 440, 121 |
| 2 | 419, 472, 220, 121 |
| 2 | 419, 236, 110, 121 |
| 11 | 419, 118, 55, 121 |
| 419, 118, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 419 x 118 x 5 x 11 = 239299280
Therefore, the lowest common multiple of 838,944,440,121 is 239299280.
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.
838 x 944 x 440 x 121 = 42116673280
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.
838 : 1, 2, 419, 838
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,944,440,121, is 1.
Now, the common factors can be found like this.
838:2x 419
944:2x 2x 2x 2x 59
440:2x 2x 2x 5x 11
121:11x 11
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 11 = 176
Therefore, the value for common factors is 176.
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 = 42116673280/(1x176)
LCM = 42116673280/176
LCM = 239299280
Thus, we can understand that the LCM of 838,944,440,121 is 239299280.
