The LCM of 777,506,693,989 is 50717898.
Find LCM of 777,506,693,989 with Prime Factorization
| 3 | 777, 506, 693, 989 |
| 7 | 259, 506, 231, 989 |
| 11 | 37, 506, 33, 989 |
| 23 | 37, 46, 3, 989 |
| 37, 2, 3, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 23 x 37 x 2 x 3 x 43 = 50717898
Therefore, the lowest common multiple of 777,506,693,989 is 50717898.
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 506 x 693 x 989 = 269464192074
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
506 : 1, 2, 11, 22, 23, 46, 253, 506
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,506,693,989, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
506:2x 11x 23
693:3x 3x 7x 11
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11x 23 = 5313
Therefore, the value for common factors is 5313.
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 = 269464192074/(1x5313)
LCM = 269464192074/5313
LCM = 50717898
Thus, we can understand that the LCM of 777,506,693,989 is 50717898.
