Given numbers are 819,403,856,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,403,856,938 is 1456109928.
Find LCM of 819,403,856,938 with Prime Factorization
| 2 | 819, 403, 856, 938 |
| 7 | 819, 403, 428, 469 |
| 13 | 117, 403, 428, 67 |
| 9, 31, 428, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 9 x 31 x 428 x 67 = 1456109928
Therefore, the lowest common multiple of 819,403,856,938 is 1456109928.
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.
819 x 403 x 856 x 938 = 265012006896
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
403 : 1, 13, 31, 403
856 : 1, 2, 4, 8, 107, 214, 428, 856
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,403,856,938, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
403:13x 31
856:2x 2x 2x 107
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 265012006896/(1x182)
LCM = 265012006896/182
LCM = 1456109928
Thus, we can understand that the LCM of 819,403,856,938 is 1456109928.
