Given numbers are 649,699,921,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,699,921,187 is 2367604569.
Find LCM of 649,699,921,187 with Prime Factorization
| 3 | 649, 699, 921, 187 |
| 11 | 649, 233, 307, 187 |
| 59, 233, 307, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 59 x 233 x 307 x 17 = 2367604569
Therefore, the lowest common multiple of 649,699,921,187 is 2367604569.
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.
649 x 699 x 921 x 187 = 78130950777
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.
649 : 1, 11, 59, 649
699 : 1, 3, 233, 699
921 : 1, 3, 307, 921
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,699,921,187, is 1.
Now, the common factors can be found like this.
649:11x 59
699:3x 233
921:3x 307
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 78130950777/(1x33)
LCM = 78130950777/33
LCM = 2367604569
Thus, we can understand that the LCM of 649,699,921,187 is 2367604569.
