Given numbers are 878,478,860,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 878,478,860,561 is 50620185660.
Find LCM of 878,478,860,561 with Prime Factorization
2 | 878, 478, 860, 561 |
439, 239, 430, 561 |
Multiply the prime numbers at the bottom and the left side.
2 x 439 x 239 x 430 x 561 = 50620185660
Therefore, the lowest common multiple of 878,478,860,561 is 50620185660.
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.
878 x 478 x 860 x 561 = 202480742640
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.
878 : 1, 2, 439, 878
478 : 1, 2, 239, 478
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
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 878,478,860,561, is 1.
Now, the common factors can be found like this.
878:2x 439
478:2x 239
860:2x 2x 5x 43
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 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 = 202480742640/(1x4)
LCM = 202480742640/4
LCM = 50620185660
Thus, we can understand that the LCM of 878,478,860,561 is 50620185660.
