Given numbers are 873,140,887,782,903
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 873,140,887,782,903 is 1822682870820.
Find LCM of 873,140,887,782,903 with Prime Factorization
2 | 873, 140, 887, 782, 903 |
3 | 873, 70, 887, 391, 903 |
7 | 291, 70, 887, 391, 301 |
291, 10, 887, 391, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 291 x 10 x 887 x 391 x 43 = 1822682870820
Therefore, the lowest common multiple of 873,140,887,782,903 is 1822682870820.
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.
873 x 140 x 887 x 782 x 903 = 76552680574440
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.
873 : 1, 3, 9, 97, 291, 873
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
887 : 1, 887
782 : 1, 2, 17, 23, 34, 46, 391, 782
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,140,887,782,903, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
140:2x 2x 5x 7
887:887
782:2x 17x 23
903:3x 7x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 76552680574440/(1x42)
LCM = 76552680574440/42
LCM = 1822682870820
Thus, we can understand that the LCM of 873,140,887,782,903 is 1822682870820.
