Given numbers are 137,693,642,847,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,693,642,847,836 is 8492662332.
Find LCM of 137,693,642,847,836 with Prime Factorization
| 2 | 137, 693, 642, 847, 836 |
| 3 | 137, 693, 321, 847, 418 |
| 7 | 137, 231, 107, 847, 418 |
| 11 | 137, 33, 107, 121, 418 |
| 137, 3, 107, 11, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 137 x 3 x 107 x 11 x 38 = 8492662332
Therefore, the lowest common multiple of 137,693,642,847,836 is 8492662332.
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.
137 x 693 x 642 x 847 x 836 = 43159709971224
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.
137 : 1, 137
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
642 : 1, 2, 3, 6, 107, 214, 321, 642
847 : 1, 7, 11, 77, 121, 847
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,693,642,847,836, is 1.
Now, the common factors can be found like this.
137:137
693:3x 3x 7x 11
642:2x 3x 107
847:7x 11x 11
836:2x 2x 11x 19
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 7x 11x 11 = 5082
Therefore, the value for common factors is 5082.
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 = 43159709971224/(1x5082)
LCM = 43159709971224/5082
LCM = 8492662332
Thus, we can understand that the LCM of 137,693,642,847,836 is 8492662332.
