The LCM of 792,490,869,765 is 260595720.
Find LCM of 792,490,869,765 with Prime Factorization
| 2 | 792, 490, 869, 765 |
| 3 | 396, 245, 869, 765 |
| 3 | 132, 245, 869, 255 |
| 5 | 44, 245, 869, 85 |
| 11 | 44, 49, 869, 17 |
| 4, 49, 79, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 4 x 49 x 79 x 17 = 260595720
Therefore, the lowest common multiple of 792,490,869,765 is 260595720.
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 490 x 869 x 765 = 257989762800
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
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
869 : 1, 11, 79, 869
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,490,869,765, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
490:2x 5x 7x 7
869:11x 79
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 257989762800/(1x990)
LCM = 257989762800/990
LCM = 260595720
Thus, we can understand that the LCM of 792,490,869,765 is 260595720.
