Given numbers are 775,919,494,680,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,919,494,680,561 is 789527052600.
Find LCM of 775,919,494,680,561 with Prime Factorization
| 2 | 775, 919, 494, 680, 561 |
| 5 | 775, 919, 247, 340, 561 |
| 17 | 155, 919, 247, 68, 561 |
| 155, 919, 247, 4, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 155 x 919 x 247 x 4 x 33 = 789527052600
Therefore, the lowest common multiple of 775,919,494,680,561 is 789527052600.
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.
775 x 919 x 494 x 680 x 561 = 134219598942000
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.
775 : 1, 5, 25, 31, 155, 775
919 : 1, 919
494 : 1, 2, 13, 19, 26, 38, 247, 494
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,919,494,680,561, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
919:919
494:2x 13x 19
680:2x 2x 2x 5x 17
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 134219598942000/(1x170)
LCM = 134219598942000/170
LCM = 789527052600
Thus, we can understand that the LCM of 775,919,494,680,561 is 789527052600.
