The LCM of 777,840,910,824 is 41616120.
Find LCM of 777,840,910,824 with Prime Factorization
| 2 | 777, 840, 910, 824 |
| 2 | 777, 420, 455, 412 |
| 2 | 777, 210, 455, 206 |
| 3 | 777, 105, 455, 103 |
| 5 | 259, 35, 455, 103 |
| 7 | 259, 7, 91, 103 |
| 37, 1, 13, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 37 x 1 x 13 x 103 = 41616120
Therefore, the lowest common multiple of 777,840,910,824 is 41616120.
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 840 x 910 x 824 = 489405571200
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
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
824 : 1, 2, 4, 8, 103, 206, 412, 824
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,840,910,824, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
840:2x 2x 2x 3x 5x 7
910:2x 5x 7x 13
824:2x 2x 2x 103
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 2x 2x 3x 5x 7x 7 = 11760
Therefore, the value for common factors is 11760.
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 = 489405571200/(1x11760)
LCM = 489405571200/11760
LCM = 41616120
Thus, we can understand that the LCM of 777,840,910,824 is 41616120.
