Given numbers are 986,936,406,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,936,406,845 is 209958840.
Find LCM of 986,936,406,845 with Prime Factorization
2 | 986, 936, 406, 845 |
13 | 493, 468, 203, 845 |
29 | 493, 36, 203, 65 |
17, 36, 7, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 17 x 36 x 7 x 65 = 209958840
Therefore, the lowest common multiple of 986,936,406,845 is 209958840.
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.
986 x 936 x 406 x 845 = 316617930720
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
406 : 1, 2, 7, 14, 29, 58, 203, 406
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,936,406,845, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
936:2x 2x 2x 3x 3x 13
406:2x 7x 29
845:5x 13x 13
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 13x 29 = 1508
Therefore, the value for common factors is 1508.
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 = 316617930720/(1x1508)
LCM = 316617930720/1508
LCM = 209958840
Thus, we can understand that the LCM of 986,936,406,845 is 209958840.
