Given numbers are 966,788,138,682
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 966,788,138,682 is 129785964.
Find LCM of 966,788,138,682 with Prime Factorization
| 2 | 966, 788, 138, 682 |
| 3 | 483, 394, 69, 341 |
| 23 | 161, 394, 23, 341 |
| 7, 394, 1, 341 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 7 x 394 x 1 x 341 = 129785964
Therefore, the lowest common multiple of 966,788,138,682 is 129785964.
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.
966 x 788 x 138 x 682 = 71641852128
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
788 : 1, 2, 4, 197, 394, 788
138 : 1, 2, 3, 6, 23, 46, 69, 138
682 : 1, 2, 11, 22, 31, 62, 341, 682
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,788,138,682, is 2.
Now, the common factors can be found like this.
966:2x 3x 7x 23
788:2x 2x 197
138:2x 3x 23
682:2x 11x 31
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 3x 23 = 276
Therefore, the value for common factors is 276.
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 = 71641852128/(2x276)
LCM = 71641852128/552
LCM = 129785964
Thus, we can understand that the LCM of 966,788,138,682 is 129785964.
