Given numbers are 343,156,903,538,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,156,903,538,140 is 3094635180.
Find LCM of 343,156,903,538,140 with Prime Factorization
| 2 | 343, 156, 903, 538, 140 |
| 2 | 343, 78, 903, 269, 70 |
| 3 | 343, 39, 903, 269, 35 |
| 7 | 343, 13, 301, 269, 35 |
| 49, 13, 43, 269, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 49 x 13 x 43 x 269 x 5 = 3094635180
Therefore, the lowest common multiple of 343,156,903,538,140 is 3094635180.
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.
343 x 156 x 903 x 538 x 140 = 3639290971680
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.
343 : 1, 7, 49, 343
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
903 : 1, 3, 7, 21, 43, 129, 301, 903
538 : 1, 2, 269, 538
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,156,903,538,140, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
156:2x 2x 3x 13
903:3x 7x 43
538:2x 269
140:2x 2x 5x 7
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 2x 3x 7x 7 = 1176
Therefore, the value for common factors is 1176.
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 = 3639290971680/(1x1176)
LCM = 3639290971680/1176
LCM = 3094635180
Thus, we can understand that the LCM of 343,156,903,538,140 is 3094635180.
