Given numbers are 821,273,815,878,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,273,815,878,145 is 4651102673490.
Find LCM of 821,273,815,878,145 with Prime Factorization
5 | 821, 273, 815, 878, 145 |
821, 273, 163, 878, 29 |
Multiply the prime numbers at the bottom and the left side.
5 x 821 x 273 x 163 x 878 x 29 = 4651102673490
Therefore, the lowest common multiple of 821,273,815,878,145 is 4651102673490.
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.
821 x 273 x 815 x 878 x 145 = 23255513367450
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.
821 : 1, 821
273 : 1, 3, 7, 13, 21, 39, 91, 273
815 : 1, 5, 163, 815
878 : 1, 2, 439, 878
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,273,815,878,145, is 1.
Now, the common factors can be found like this.
821:821
273:3x 7x 13
815:5x 163
878:2x 439
145:5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 23255513367450/(1x5)
LCM = 23255513367450/5
LCM = 4651102673490
Thus, we can understand that the LCM of 821,273,815,878,145 is 4651102673490.
