Given numbers are 878,715,649,646,888
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 878,715,649,646,888 is 5311755323160.
Find LCM of 878,715,649,646,888 with Prime Factorization
| 2 | 878, 715, 649, 646, 888 |
| 11 | 439, 715, 649, 323, 444 |
| 439, 65, 59, 323, 444 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 439 x 65 x 59 x 323 x 444 = 5311755323160
Therefore, the lowest common multiple of 878,715,649,646,888 is 5311755323160.
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 715 x 649 x 646 x 888 = 233717234219040
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
649 : 1, 11, 59, 649
646 : 1, 2, 17, 19, 34, 38, 323, 646
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,715,649,646,888, is 1.
Now, the common factors can be found like this.
878:2x 439
715:5x 11x 13
649:11x 59
646:2x 17x 19
888:2x 2x 2x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 233717234219040/(1x44)
LCM = 233717234219040/44
LCM = 5311755323160
Thus, we can understand that the LCM of 878,715,649,646,888 is 5311755323160.
