Given numbers are 969,138,615,597,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,138,615,597,870 is 52733493570.
Find LCM of 969,138,615,597,870 with Prime Factorization
| 2 | 969, 138, 615, 597, 870 |
| 3 | 969, 69, 615, 597, 435 |
| 5 | 323, 23, 205, 199, 145 |
| 323, 23, 41, 199, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 323 x 23 x 41 x 199 x 29 = 52733493570
Therefore, the lowest common multiple of 969,138,615,597,870 is 52733493570.
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.
969 x 138 x 615 x 597 x 870 = 42714129791700
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
138 : 1, 2, 3, 6, 23, 46, 69, 138
615 : 1, 3, 5, 15, 41, 123, 205, 615
597 : 1, 3, 199, 597
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,138,615,597,870, is 3.
Now, the common factors can be found like this.
969:3x 17x 19
138:2x 3x 23
615:3x 5x 41
597:3x 199
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 42714129791700/(3x270)
LCM = 42714129791700/810
LCM = 52733493570
Thus, we can understand that the LCM of 969,138,615,597,870 is 52733493570.
