Given numbers are 591,777,900,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,777,900,392 is 642889800.
Find LCM of 591,777,900,392 with Prime Factorization
| 2 | 591, 777, 900, 392 |
| 2 | 591, 777, 450, 196 |
| 3 | 591, 777, 225, 98 |
| 7 | 197, 259, 75, 98 |
| 197, 37, 75, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 197 x 37 x 75 x 14 = 642889800
Therefore, the lowest common multiple of 591,777,900,392 is 642889800.
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.
591 x 777 x 900 x 392 = 162008229600
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.
591 : 1, 3, 197, 591
777 : 1, 3, 7, 21, 37, 111, 259, 777
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,777,900,392, is 1.
Now, the common factors can be found like this.
591:3x 197
777:3x 7x 37
900:2x 2x 3x 3x 5x 5
392:2x 2x 2x 7x 7
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 162008229600/(1x252)
LCM = 162008229600/252
LCM = 642889800
Thus, we can understand that the LCM of 591,777,900,392 is 642889800.
