Given numbers are 969,508,646,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,508,646,385 is 189517020.
Find LCM of 969,508,646,385 with Prime Factorization
| 2 | 969, 508, 646, 385 |
| 17 | 969, 254, 323, 385 |
| 19 | 57, 254, 19, 385 |
| 3, 254, 1, 385 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 3 x 254 x 1 x 385 = 189517020
Therefore, the lowest common multiple of 969,508,646,385 is 189517020.
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 508 x 646 x 385 = 122427994920
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
508 : 1, 2, 4, 127, 254, 508
646 : 1, 2, 17, 19, 34, 38, 323, 646
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,508,646,385, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
508:2x 2x 127
646:2x 17x 19
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 19 = 646
Therefore, the value for common factors is 646.
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 = 122427994920/(1x646)
LCM = 122427994920/646
LCM = 189517020
Thus, we can understand that the LCM of 969,508,646,385 is 189517020.
