Given numbers are 297,902,420,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,902,420,738 is 1704780.
Find LCM of 297,902,420,738 with Prime Factorization
| 2 | 297, 902, 420, 738 |
| 3 | 297, 451, 210, 369 |
| 3 | 99, 451, 70, 123 |
| 11 | 33, 451, 70, 41 |
| 41 | 3, 41, 70, 41 |
| 3, 1, 70, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 41 x 3 x 1 x 70 x 1 = 1704780
Therefore, the lowest common multiple of 297,902,420,738 is 1704780.
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.
297 x 902 x 420 x 738 = 83036424240
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
902 : 1, 2, 11, 22, 41, 82, 451, 902
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,902,420,738, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
902:2x 11x 41
420:2x 2x 3x 5x 7
738:2x 3x 3x 41
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 3x 11x 41 = 48708
Therefore, the value for common factors is 48708.
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 = 83036424240/(1x48708)
LCM = 83036424240/48708
LCM = 1704780
Thus, we can understand that the LCM of 297,902,420,738 is 1704780.
