Find LCM of 774,711,723,407,836 with Prime Factorization
| 2 | 774, 711, 723, 407, 836 |
| 3 | 387, 711, 723, 407, 418 |
| 3 | 129, 237, 241, 407, 418 |
| 11 | 43, 79, 241, 407, 418 |
| 43, 79, 241, 37, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 43 x 79 x 241 x 37 x 38 = 227909852676
Therefore, the lowest common multiple of 774,711,723,407,836 is 227909852676.
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.
774 x 711 x 723 x 407 x 836 = 135378452489544
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
711 : 1, 3, 9, 79, 237, 711
723 : 1, 3, 241, 723
407 : 1, 11, 37, 407
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 774,711,723,407,836, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
711:3x 3x 79
723:3x 241
407:11x 37
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 3x 3x 11 = 594
Therefore, the value for common factors is 594.
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 = 135378452489544/(1x594)
LCM = 135378452489544/594
LCM = 227909852676
Thus, we can understand that the LCM of 774,711,723,407,836 is 227909852676.
