Given numbers are 777,694,694,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,694,694,489 is 87895794.
Find LCM of 777,694,694,489 with Prime Factorization
| 2 | 777, 694, 694, 489 |
| 3 | 777, 347, 347, 489 |
| 347 | 259, 347, 347, 163 |
| 259, 1, 1, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 347 x 259 x 1 x 1 x 163 = 87895794
Therefore, the lowest common multiple of 777,694,694,489 is 87895794.
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 694 x 694 x 489 = 182999043108
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
694 : 1, 2, 347, 694
694 : 1, 2, 347, 694
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,694,694,489, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
694:2x 347
694:2x 347
489:3x 163
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 347 = 2082
Therefore, the value for common factors is 2082.
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 = 182999043108/(1x2082)
LCM = 182999043108/2082
LCM = 87895794
Thus, we can understand that the LCM of 777,694,694,489 is 87895794.
