Given numbers are 731,649,935,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,649,935,623 is 1477815185.
Find LCM of 731,649,935,623 with Prime Factorization
| 11 | 731, 649, 935, 623 |
| 17 | 731, 59, 85, 623 |
| 43, 59, 5, 623 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 43 x 59 x 5 x 623 = 1477815185
Therefore, the lowest common multiple of 731,649,935,623 is 1477815185.
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.
731 x 649 x 935 x 623 = 276351439595
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.
731 : 1, 17, 43, 731
649 : 1, 11, 59, 649
935 : 1, 5, 11, 17, 55, 85, 187, 935
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,649,935,623, is 1.
Now, the common factors can be found like this.
731:17x 43
649:11x 59
935:5x 11x 17
623:7x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 276351439595/(1x187)
LCM = 276351439595/187
LCM = 1477815185
Thus, we can understand that the LCM of 731,649,935,623 is 1477815185.
