Find LCM of 777,489,711,703,861 with Prime Factorization
3 | 777, 489, 711, 703, 861 |
7 | 259, 163, 237, 703, 287 |
37 | 37, 163, 237, 703, 41 |
1, 163, 237, 19, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 37 x 1 x 163 x 237 x 19 x 41 = 23382687573
Therefore, the lowest common multiple of 777,489,711,703,861 is 23382687573.
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.
777 x 489 x 711 x 703 x 861 = 163515134197989
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
489 : 1, 3, 163, 489
711 : 1, 3, 9, 79, 237, 711
703 : 1, 19, 37, 703
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,489,711,703,861, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
489:3x 163
711:3x 3x 79
703:19x 37
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 37 = 6993
Therefore, the value for common factors is 6993.
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 = 163515134197989/(1x6993)
LCM = 163515134197989/6993
LCM = 23382687573
Thus, we can understand that the LCM of 777,489,711,703,861 is 23382687573.
