Given numbers are 686,668,693,935,853
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,668,693,935,853 is 1644650926380.
Find LCM of 686,668,693,935,853 with Prime Factorization
| 2 | 686, 668, 693, 935, 853 |
| 7 | 343, 334, 693, 935, 853 |
| 11 | 49, 334, 99, 935, 853 |
| 49, 334, 9, 85, 853 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 49 x 334 x 9 x 85 x 853 = 1644650926380
Therefore, the lowest common multiple of 686,668,693,935,853 is 1644650926380.
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.
686 x 668 x 693 x 935 x 853 = 253276242662520
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
668 : 1, 2, 4, 167, 334, 668
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
935 : 1, 5, 11, 17, 55, 85, 187, 935
853 : 1, 853
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,668,693,935,853, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
668:2x 2x 167
693:3x 3x 7x 11
935:5x 11x 17
853:853
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 253276242662520/(1x154)
LCM = 253276242662520/154
LCM = 1644650926380
Thus, we can understand that the LCM of 686,668,693,935,853 is 1644650926380.
