Given numbers are 969,680,605,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,680,605,189 is 295467480.
Find LCM of 969,680,605,189 with Prime Factorization
| 3 | 969, 680, 605, 189 |
| 5 | 323, 680, 605, 63 |
| 17 | 323, 136, 121, 63 |
| 19, 8, 121, 63 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 19 x 8 x 121 x 63 = 295467480
Therefore, the lowest common multiple of 969,680,605,189 is 295467480.
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 680 x 605 x 189 = 75344207400
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
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
605 : 1, 5, 11, 55, 121, 605
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,680,605,189, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
680:2x 2x 2x 5x 17
605:5x 11x 11
189:3x 3x 3x 7
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 17 = 255
Therefore, the value for common factors is 255.
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 = 75344207400/(1x255)
LCM = 75344207400/255
LCM = 295467480
Thus, we can understand that the LCM of 969,680,605,189 is 295467480.
