Given numbers are 829,686,661,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 829,686,661,102 is 19171243434.
Find LCM of 829,686,661,102 with Prime Factorization
| 2 | 829, 686, 661, 102 |
| 829, 343, 661, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 829 x 343 x 661 x 51 = 19171243434
Therefore, the lowest common multiple of 829,686,661,102 is 19171243434.
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.
829 x 686 x 661 x 102 = 38342486868
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.
829 : 1, 829
686 : 1, 2, 7, 14, 49, 98, 343, 686
661 : 1, 661
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,686,661,102, is 1.
Now, the common factors can be found like this.
829:829
686:2x 7x 7x 7
661:661
102:2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 38342486868/(1x2)
LCM = 38342486868/2
LCM = 19171243434
Thus, we can understand that the LCM of 829,686,661,102 is 19171243434.
