Given numbers are 649,657,957,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,657,957,198 is 24730794.
Find LCM of 649,657,957,198 with Prime Factorization
| 3 | 649, 657, 957, 198 |
| 3 | 649, 219, 319, 66 |
| 11 | 649, 73, 319, 22 |
| 59, 73, 29, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 59 x 73 x 29 x 2 = 24730794
Therefore, the lowest common multiple of 649,657,957,198 is 24730794.
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 657 x 957 x 198 = 80795503998
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
657 : 1, 3, 9, 73, 219, 657
957 : 1, 3, 11, 29, 33, 87, 319, 957
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,657,957,198, is 1.
Now, the common factors can be found like this.
649:11x 59
657:3x 3x 73
957:3x 11x 29
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 11x 11 = 3267
Therefore, the value for common factors is 3267.
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 = 80795503998/(1x3267)
LCM = 80795503998/3267
LCM = 24730794
Thus, we can understand that the LCM of 649,657,957,198 is 24730794.
