The LCM of 923,702,550,855 is 260424450.
Find LCM of 923,702,550,855 with Prime Factorization
| 2 | 923, 702, 550, 855 |
| 3 | 923, 351, 275, 855 |
| 3 | 923, 117, 275, 285 |
| 5 | 923, 39, 275, 95 |
| 13 | 923, 39, 55, 19 |
| 71, 3, 55, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 71 x 3 x 55 x 19 = 260424450
Therefore, the lowest common multiple of 923,702,550,855 is 260424450.
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.
923 x 702 x 550 x 855 = 304696606500
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.
923 : 1, 13, 71, 923
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,702,550,855, is 1.
Now, the common factors can be found like this.
923:13x 71
702:2x 3x 3x 3x 13
550:2x 5x 5x 11
855:3x 3x 5x 19
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 13 = 1170
Therefore, the value for common factors is 1170.
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 = 304696606500/(1x1170)
LCM = 304696606500/1170
LCM = 260424450
Thus, we can understand that the LCM of 923,702,550,855 is 260424450.
