Given numbers are 349,923,689,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 349,923,689,901 is 290236427.
Find LCM of 349,923,689,901 with Prime Factorization
| 13 | 349, 923, 689, 901 |
| 53 | 349, 71, 53, 901 |
| 349, 71, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 349 x 71 x 1 x 17 = 290236427
Therefore, the lowest common multiple of 349,923,689,901 is 290236427.
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 923 x 689 x 901 = 199972898203
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
923 : 1, 13, 71, 923
689 : 1, 13, 53, 689
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 349,923,689,901, is 1.
Now, the common factors can be found like this.
349:349
923:13x 71
689:13x 53
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 53 = 689
Therefore, the value for common factors is 689.
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 = 199972898203/(1x689)
LCM = 199972898203/689
LCM = 290236427
Thus, we can understand that the LCM of 349,923,689,901 is 290236427.
