Given numbers are 916,784,795,439,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 916,784,795,439,871 is 54575955623280.
Find LCM of 916,784,795,439,871 with Prime Factorization
| 2 | 916, 784, 795, 439, 871 |
| 2 | 458, 392, 795, 439, 871 |
| 229, 196, 795, 439, 871 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 229 x 196 x 795 x 439 x 871 = 54575955623280
Therefore, the lowest common multiple of 916,784,795,439,871 is 54575955623280.
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.
916 x 784 x 795 x 439 x 871 = 218303822493120
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.
916 : 1, 2, 4, 229, 458, 916
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
795 : 1, 3, 5, 15, 53, 159, 265, 795
439 : 1, 439
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,784,795,439,871, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
784:2x 2x 2x 2x 7x 7
795:3x 5x 53
439:439
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 218303822493120/(1x4)
LCM = 218303822493120/4
LCM = 54575955623280
Thus, we can understand that the LCM of 916,784,795,439,871 is 54575955623280.
