Given numbers are 909,254,847,615,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,254,847,615,768 is 5131505998080.
Find LCM of 909,254,847,615,768 with Prime Factorization
| 2 | 909, 254, 847, 615, 768 |
| 3 | 909, 127, 847, 615, 384 |
| 303, 127, 847, 205, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 303 x 127 x 847 x 205 x 128 = 5131505998080
Therefore, the lowest common multiple of 909,254,847,615,768 is 5131505998080.
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.
909 x 254 x 847 x 615 x 768 = 92367107965440
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.
909 : 1, 3, 9, 101, 303, 909
254 : 1, 2, 127, 254
847 : 1, 7, 11, 77, 121, 847
615 : 1, 3, 5, 15, 41, 123, 205, 615
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,254,847,615,768, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
254:2x 127
847:7x 11x 11
615:3x 5x 41
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 = 92367107965440/(1x18)
LCM = 92367107965440/18
LCM = 5131505998080
Thus, we can understand that the LCM of 909,254,847,615,768 is 5131505998080.
