Given numbers are 681,685,645,946,935
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,685,645,946,935 is 7502011770.
Find LCM of 681,685,645,946,935 with Prime Factorization
| 3 | 681, 685, 645, 946, 935 |
| 5 | 227, 685, 215, 946, 935 |
| 11 | 227, 137, 43, 946, 187 |
| 43 | 227, 137, 43, 86, 17 |
| 227, 137, 1, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 43 x 227 x 137 x 1 x 2 x 17 = 7502011770
Therefore, the lowest common multiple of 681,685,645,946,935 is 7502011770.
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.
681 x 685 x 645 x 946 x 935 = 266133867540750
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.
681 : 1, 3, 227, 681
685 : 1, 5, 137, 685
645 : 1, 3, 5, 15, 43, 129, 215, 645
946 : 1, 2, 11, 22, 43, 86, 473, 946
935 : 1, 5, 11, 17, 55, 85, 187, 935
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,685,645,946,935, is 1.
Now, the common factors can be found like this.
681:3x 227
685:5x 137
645:3x 5x 43
946:2x 11x 43
935:5x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11x 43 = 35475
Therefore, the value for common factors is 35475.
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 = 266133867540750/(1x35475)
LCM = 266133867540750/35475
LCM = 7502011770
Thus, we can understand that the LCM of 681,685,645,946,935 is 7502011770.
