Given numbers are 821,652,889,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,652,889,382 is 90892046308.
Find LCM of 821,652,889,382 with Prime Factorization
| 2 | 821, 652, 889, 382 |
| 821, 326, 889, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 821 x 326 x 889 x 191 = 90892046308
Therefore, the lowest common multiple of 821,652,889,382 is 90892046308.
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 652 x 889 x 382 = 181784092616
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
652 : 1, 2, 4, 163, 326, 652
889 : 1, 7, 127, 889
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,652,889,382, is 1.
Now, the common factors can be found like this.
821:821
652:2x 2x 163
889:7x 127
382:2x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 181784092616/(1x2)
LCM = 181784092616/2
LCM = 90892046308
Thus, we can understand that the LCM of 821,652,889,382 is 90892046308.
