Given numbers are 638,969,850,932,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,969,850,932,869 is 568980617700.
Find LCM of 638,969,850,932,869 with Prime Factorization
| 2 | 638, 969, 850, 932, 869 |
| 11 | 319, 969, 425, 466, 869 |
| 17 | 29, 969, 425, 466, 79 |
| 29, 57, 25, 466, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 29 x 57 x 25 x 466 x 79 = 568980617700
Therefore, the lowest common multiple of 638,969,850,932,869 is 568980617700.
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.
638 x 969 x 850 x 932 x 869 = 425597502039600
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
969 : 1, 3, 17, 19, 51, 57, 323, 969
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
932 : 1, 2, 4, 233, 466, 932
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,969,850,932,869, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
969:3x 17x 19
850:2x 5x 5x 17
932:2x 2x 233
869:11x 79
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 425597502039600/(1x748)
LCM = 425597502039600/748
LCM = 568980617700
Thus, we can understand that the LCM of 638,969,850,932,869 is 568980617700.
