Given numbers are 856,434,651,418,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,434,651,418,388 is 11297250888.
Find LCM of 856,434,651,418,388 with Prime Factorization
| 2 | 856, 434, 651, 418, 388 |
| 2 | 428, 217, 651, 209, 194 |
| 7 | 214, 217, 651, 209, 97 |
| 31 | 214, 31, 93, 209, 97 |
| 214, 1, 3, 209, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 31 x 214 x 1 x 3 x 209 x 97 = 11297250888
Therefore, the lowest common multiple of 856,434,651,418,388 is 11297250888.
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.
856 x 434 x 651 x 418 x 388 = 39224055083136
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
434 : 1, 2, 7, 14, 31, 62, 217, 434
651 : 1, 3, 7, 21, 31, 93, 217, 651
418 : 1, 2, 11, 19, 22, 38, 209, 418
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,434,651,418,388, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
434:2x 7x 31
651:3x 7x 31
418:2x 11x 19
388:2x 2x 97
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 2x 2x 7x 31 = 3472
Therefore, the value for common factors is 3472.
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 = 39224055083136/(1x3472)
LCM = 39224055083136/3472
LCM = 11297250888
Thus, we can understand that the LCM of 856,434,651,418,388 is 11297250888.
