Given numbers are 615,969,972,794
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,969,972,794 is 25551309060.
Find LCM of 615,969,972,794 with Prime Factorization
| 2 | 615, 969, 972, 794 |
| 3 | 615, 969, 486, 397 |
| 205, 323, 162, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 205 x 323 x 162 x 397 = 25551309060
Therefore, the lowest common multiple of 615,969,972,794 is 25551309060.
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.
615 x 969 x 972 x 794 = 459923563080
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
969 : 1, 3, 17, 19, 51, 57, 323, 969
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
794 : 1, 2, 397, 794
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,969,972,794, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
969:3x 17x 19
972:2x 2x 3x 3x 3x 3x 3
794:2x 397
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 3 = 18
Therefore, the value for common factors is 18.
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 = 459923563080/(1x18)
LCM = 459923563080/18
LCM = 25551309060
Thus, we can understand that the LCM of 615,969,972,794 is 25551309060.
