Given numbers are 626,731,978,841,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 626,731,978,841,798 is 25029271315902.
Find LCM of 626,731,978,841,798 with Prime Factorization
| 2 | 626, 731, 978, 841, 798 |
| 3 | 313, 731, 489, 841, 399 |
| 313, 731, 163, 841, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 313 x 731 x 163 x 841 x 133 = 25029271315902
Therefore, the lowest common multiple of 626,731,978,841,798 is 25029271315902.
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.
626 x 731 x 978 x 841 x 798 = 300351255790824
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.
626 : 1, 2, 313, 626
731 : 1, 17, 43, 731
978 : 1, 2, 3, 6, 163, 326, 489, 978
841 : 1, 29, 841
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,731,978,841,798, is 1.
Now, the common factors can be found like this.
626:2x 313
731:17x 43
978:2x 3x 163
841:29x 29
798:2x 3x 7x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 300351255790824/(1x12)
LCM = 300351255790824/12
LCM = 25029271315902
Thus, we can understand that the LCM of 626,731,978,841,798 is 25029271315902.
