Given numbers are 745,644,873,649,968
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,644,873,649,968 is 5980310887320.
Find LCM of 745,644,873,649,968 with Prime Factorization
| 2 | 745, 644, 873, 649, 968 |
| 2 | 745, 322, 873, 649, 484 |
| 11 | 745, 161, 873, 649, 242 |
| 745, 161, 873, 59, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 745 x 161 x 873 x 59 x 22 = 5980310887320
Therefore, the lowest common multiple of 745,644,873,649,968 is 5980310887320.
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.
745 x 644 x 873 x 649 x 968 = 263133679042080
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.
745 : 1, 5, 149, 745
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
873 : 1, 3, 9, 97, 291, 873
649 : 1, 11, 59, 649
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,644,873,649,968, is 1.
Now, the common factors can be found like this.
745:5x 149
644:2x 2x 7x 23
873:3x 3x 97
649:11x 59
968:2x 2x 2x 11x 11
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 11 = 44
Therefore, the value for common factors is 44.
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 = 263133679042080/(1x44)
LCM = 263133679042080/44
LCM = 5980310887320
Thus, we can understand that the LCM of 745,644,873,649,968 is 5980310887320.
