Given numbers are 281,804,270,740
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,804,270,740 is 376163460.
Find LCM of 281,804,270,740 with Prime Factorization
| 2 | 281, 804, 270, 740 |
| 2 | 281, 402, 135, 370 |
| 3 | 281, 201, 135, 185 |
| 5 | 281, 67, 45, 185 |
| 281, 67, 9, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 281 x 67 x 9 x 37 = 376163460
Therefore, the lowest common multiple of 281,804,270,740 is 376163460.
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.
281 x 804 x 270 x 740 = 45139615200
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.
281 : 1, 281
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,804,270,740, is 1.
Now, the common factors can be found like this.
281:281
804:2x 2x 3x 67
270:2x 3x 3x 3x 5
740:2x 2x 5x 37
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 45139615200/(1x120)
LCM = 45139615200/120
LCM = 376163460
Thus, we can understand that the LCM of 281,804,270,740 is 376163460.
