Given numbers are 555,905,869,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 555,905,869,777 is 611067765.
Find LCM of 555,905,869,777 with Prime Factorization
| 3 | 555, 905, 869, 777 |
| 5 | 185, 905, 869, 259 |
| 37 | 37, 181, 869, 259 |
| 1, 181, 869, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 37 x 1 x 181 x 869 x 7 = 611067765
Therefore, the lowest common multiple of 555,905,869,777 is 611067765.
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.
555 x 905 x 869 x 777 = 339142609575
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
905 : 1, 5, 181, 905
869 : 1, 11, 79, 869
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,905,869,777, is 1.
Now, the common factors can be found like this.
555:3x 5x 37
905:5x 181
869:11x 79
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 37 = 555
Therefore, the value for common factors is 555.
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 = 339142609575/(1x555)
LCM = 339142609575/555
LCM = 611067765
Thus, we can understand that the LCM of 555,905,869,777 is 611067765.
