Given numbers are 821,740,169,560,885
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,740,169,560,885 is 508853632560.
Find LCM of 821,740,169,560,885 with Prime Factorization
| 2 | 821, 740, 169, 560, 885 |
| 2 | 821, 370, 169, 280, 885 |
| 5 | 821, 185, 169, 140, 885 |
| 821, 37, 169, 28, 177 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 821 x 37 x 169 x 28 x 177 = 508853632560
Therefore, the lowest common multiple of 821,740,169,560,885 is 508853632560.
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 740 x 169 x 560 x 885 = 50885363256000
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
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
169 : 1, 13, 169
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,740,169,560,885, is 1.
Now, the common factors can be found like this.
821:821
740:2x 2x 5x 37
169:13x 13
560:2x 2x 2x 2x 5x 7
885:3x 5x 59
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 50885363256000/(1x100)
LCM = 50885363256000/100
LCM = 508853632560
Thus, we can understand that the LCM of 821,740,169,560,885 is 508853632560.
