Given numbers are 836,649,841,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,649,841,406 is 290370388.
Find LCM of 836,649,841,406 with Prime Factorization
| 2 | 836, 649, 841, 406 |
| 11 | 418, 649, 841, 203 |
| 29 | 38, 59, 841, 203 |
| 38, 59, 29, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 38 x 59 x 29 x 7 = 290370388
Therefore, the lowest common multiple of 836,649,841,406 is 290370388.
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.
836 x 649 x 841 x 406 = 185256307544
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
649 : 1, 11, 59, 649
841 : 1, 29, 841
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,649,841,406, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
649:11x 59
841:29x 29
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 29 = 638
Therefore, the value for common factors is 638.
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 = 185256307544/(1x638)
LCM = 185256307544/638
LCM = 290370388
Thus, we can understand that the LCM of 836,649,841,406 is 290370388.
