Given numbers are 806,338,830,985
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,338,830,985 is 856628890.
Find LCM of 806,338,830,985 with Prime Factorization
2 | 806, 338, 830, 985 |
5 | 403, 169, 415, 985 |
13 | 403, 169, 83, 197 |
31, 13, 83, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 31 x 13 x 83 x 197 = 856628890
Therefore, the lowest common multiple of 806,338,830,985 is 856628890.
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.
806 x 338 x 830 x 985 = 222723511400
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
338 : 1, 2, 13, 26, 169, 338
830 : 1, 2, 5, 10, 83, 166, 415, 830
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,338,830,985, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
338:2x 13x 13
830:2x 5x 83
985:5x 197
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 13 = 260
Therefore, the value for common factors is 260.
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 = 222723511400/(1x260)
LCM = 222723511400/260
LCM = 856628890
Thus, we can understand that the LCM of 806,338,830,985 is 856628890.
