Find LCM of 682,690,645,494,276 with Prime Factorization
2 | 682, 690, 645, 494, 276 |
3 | 341, 345, 645, 247, 138 |
5 | 341, 115, 215, 247, 46 |
23 | 341, 23, 43, 247, 46 |
341, 1, 43, 247, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 341 x 1 x 43 x 247 x 2 = 4998030180
Therefore, the lowest common multiple of 682,690,645,494,276 is 4998030180.
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.
682 x 690 x 645 x 494 x 276 = 41383689890400
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
645 : 1, 3, 5, 15, 43, 129, 215, 645
494 : 1, 2, 13, 19, 26, 38, 247, 494
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,690,645,494,276, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
690:2x 3x 5x 23
645:3x 5x 43
494:2x 13x 19
276:2x 2x 3x 23
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 3x 5x 23 = 8280
Therefore, the value for common factors is 8280.
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 = 41383689890400/(1x8280)
LCM = 41383689890400/8280
LCM = 4998030180
Thus, we can understand that the LCM of 682,690,645,494,276 is 4998030180.
