The LCM of 792,905,923,440 is 661569480.
Find LCM of 792,905,923,440 with Prime Factorization
| 2 | 792, 905, 923, 440 |
| 2 | 396, 905, 923, 220 |
| 2 | 198, 905, 923, 110 |
| 5 | 99, 905, 923, 55 |
| 11 | 99, 181, 923, 11 |
| 9, 181, 923, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 9 x 181 x 923 x 1 = 661569480
Therefore, the lowest common multiple of 792,905,923,440 is 661569480.
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.
792 x 905 x 923 x 440 = 291090571200
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.
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
905 : 1, 5, 181, 905
923 : 1, 13, 71, 923
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,905,923,440, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
905:5x 181
923:13x 71
440:2x 2x 2x 5x 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 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 291090571200/(1x440)
LCM = 291090571200/440
LCM = 661569480
Thus, we can understand that the LCM of 792,905,923,440 is 661569480.
