Given numbers are 657,789,644,919
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,789,644,919 is 102263934276.
Find LCM of 657,789,644,919 with Prime Factorization
| 3 | 657, 789, 644, 919 |
| 219, 263, 644, 919 |
Multiply the prime numbers at the bottom and the left side.
3 x 219 x 263 x 644 x 919 = 102263934276
Therefore, the lowest common multiple of 657,789,644,919 is 102263934276.
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.
657 x 789 x 644 x 919 = 306791802828
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.
657 : 1, 3, 9, 73, 219, 657
789 : 1, 3, 263, 789
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,789,644,919, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
789:3x 263
644:2x 2x 7x 23
919:919
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 306791802828/(1x3)
LCM = 306791802828/3
LCM = 102263934276
Thus, we can understand that the LCM of 657,789,644,919 is 102263934276.
