Given numbers are 248,645,989,943,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,645,989,943,899 is 4374426120.
Find LCM of 248,645,989,943,899 with Prime Factorization
| 23 | 248, 645, 989, 943, 899 |
| 31 | 248, 645, 43, 41, 899 |
| 43 | 8, 645, 43, 41, 29 |
| 8, 15, 1, 41, 29 |
Multiply the prime numbers at the bottom and the left side.
23 x 31 x 43 x 8 x 15 x 1 x 41 x 29 = 4374426120
Therefore, the lowest common multiple of 248,645,989,943,899 is 4374426120.
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.
248 x 645 x 989 x 943 x 899 = 134115530413080
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
645 : 1, 3, 5, 15, 43, 129, 215, 645
989 : 1, 23, 43, 989
943 : 1, 23, 41, 943
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,645,989,943,899, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
645:3x 5x 43
989:23x 43
943:23x 41
899:29x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 31x 43 = 30659
Therefore, the value for common factors is 30659.
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 = 134115530413080/(1x30659)
LCM = 134115530413080/30659
LCM = 4374426120
Thus, we can understand that the LCM of 248,645,989,943,899 is 4374426120.
