Find LCM of 690,242,898,263,858 with Prime Factorization
2 | 690, 242, 898, 263, 858 |
3 | 345, 121, 449, 263, 429 |
11 | 115, 121, 449, 263, 143 |
115, 11, 449, 263, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 115 x 11 x 449 x 263 x 13 = 128168087190
Therefore, the lowest common multiple of 690,242,898,263,858 is 128168087190.
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.
690 x 242 x 898 x 263 x 858 = 33836375018160
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
242 : 1, 2, 11, 22, 121, 242
898 : 1, 2, 449, 898
263 : 1, 263
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 690,242,898,263,858, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
242:2x 11x 11
898:2x 449
263:263
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 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 33836375018160/(1x264)
LCM = 33836375018160/264
LCM = 128168087190
Thus, we can understand that the LCM of 690,242,898,263,858 is 128168087190.
