Given numbers are 655,767,177,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,767,177,861 is 432553485.
Find LCM of 655,767,177,861 with Prime Factorization
| 3 | 655, 767, 177, 861 |
| 59 | 655, 767, 59, 287 |
| 655, 13, 1, 287 |
Multiply the prime numbers at the bottom and the left side.
3 x 59 x 655 x 13 x 1 x 287 = 432553485
Therefore, the lowest common multiple of 655,767,177,861 is 432553485.
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.
655 x 767 x 177 x 861 = 76561966845
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.
655 : 1, 5, 131, 655
767 : 1, 13, 59, 767
177 : 1, 3, 59, 177
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,767,177,861, is 1.
Now, the common factors can be found like this.
655:5x 131
767:13x 59
177:3x 59
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 59 = 177
Therefore, the value for common factors is 177.
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 = 76561966845/(1x177)
LCM = 76561966845/177
LCM = 432553485
Thus, we can understand that the LCM of 655,767,177,861 is 432553485.
