Given numbers are 787,787,852,863,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,787,852,863,540 is 26039799540.
Find LCM of 787,787,852,863,540 with Prime Factorization
| 2 | 787, 787, 852, 863, 540 |
| 2 | 787, 787, 426, 863, 270 |
| 3 | 787, 787, 213, 863, 135 |
| 787 | 787, 787, 71, 863, 45 |
| 1, 1, 71, 863, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 787 x 1 x 1 x 71 x 863 x 45 = 26039799540
Therefore, the lowest common multiple of 787,787,852,863,540 is 26039799540.
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.
787 x 787 x 852 x 863 x 540 = 245919866855760
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.
787 : 1, 787
787 : 1, 787
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
863 : 1, 863
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,787,852,863,540, is 1.
Now, the common factors can be found like this.
787:787
787:787
852:2x 2x 3x 71
863:863
540:2x 2x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 787 = 9444
Therefore, the value for common factors is 9444.
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 = 245919866855760/(1x9444)
LCM = 245919866855760/9444
LCM = 26039799540
Thus, we can understand that the LCM of 787,787,852,863,540 is 26039799540.
