Given numbers are 349,856,321,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 349,856,321,693 is 207029592.
Find LCM of 349,856,321,693 with Prime Factorization
| 3 | 349, 856, 321, 693 |
| 107 | 349, 856, 107, 231 |
| 349, 8, 1, 231 |
Multiply the prime numbers at the bottom and the left side.
3 x 107 x 349 x 8 x 1 x 231 = 207029592
Therefore, the lowest common multiple of 349,856,321,693 is 207029592.
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.
349 x 856 x 321 x 693 = 66456499032
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.
349 : 1, 349
856 : 1, 2, 4, 8, 107, 214, 428, 856
321 : 1, 3, 107, 321
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 349,856,321,693, is 1.
Now, the common factors can be found like this.
349:349
856:2x 2x 2x 107
321:3x 107
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 107 = 321
Therefore, the value for common factors is 321.
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 = 66456499032/(1x321)
LCM = 66456499032/321
LCM = 207029592
Thus, we can understand that the LCM of 349,856,321,693 is 207029592.
