The LCM of 550,690,663,858 is 8386950.
Find LCM of 550,690,663,858 with Prime Factorization
| 2 | 550, 690, 663, 858 |
| 3 | 275, 345, 663, 429 |
| 5 | 275, 115, 221, 143 |
| 11 | 55, 23, 221, 143 |
| 13 | 5, 23, 221, 13 |
| 5, 23, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 5 x 23 x 17 x 1 = 8386950
Therefore, the lowest common multiple of 550,690,663,858 is 8386950.
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.
550 x 690 x 663 x 858 = 215880093000
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.
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
663 : 1, 3, 13, 17, 39, 51, 221, 663
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,690,663,858, is 1.
Now, the common factors can be found like this.
550:2x 5x 5x 11
690:2x 3x 5x 23
663:3x 13x 17
858:2x 3x 11x 13
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 3x 3x 5x 11x 13 = 25740
Therefore, the value for common factors is 25740.
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 = 215880093000/(1x25740)
LCM = 215880093000/25740
LCM = 8386950
Thus, we can understand that the LCM of 550,690,663,858 is 8386950.
