Given numbers are 108,771,618,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 108,771,618,385 is 1100664180.
Find LCM of 108,771,618,385 with Prime Factorization
| 2 | 108, 771, 618, 385 |
| 3 | 54, 771, 309, 385 |
| 18, 257, 103, 385 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 18 x 257 x 103 x 385 = 1100664180
Therefore, the lowest common multiple of 108,771,618,385 is 1100664180.
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.
108 x 771 x 618 x 385 = 19811955240
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
771 : 1, 3, 257, 771
618 : 1, 2, 3, 6, 103, 206, 309, 618
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 108,771,618,385, is 1.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
771:3x 257
618:2x 3x 103
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 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 = 19811955240/(1x18)
LCM = 19811955240/18
LCM = 1100664180
Thus, we can understand that the LCM of 108,771,618,385 is 1100664180.
