Given numbers are 420,935,240,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,935,240,899 is 282429840.
Find LCM of 420,935,240,899 with Prime Factorization
| 2 | 420, 935, 240, 899 |
| 2 | 210, 935, 120, 899 |
| 3 | 105, 935, 60, 899 |
| 5 | 35, 935, 20, 899 |
| 7, 187, 4, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 187 x 4 x 899 = 282429840
Therefore, the lowest common multiple of 420,935,240,899 is 282429840.
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.
420 x 935 x 240 x 899 = 84728952000
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.
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
935 : 1, 5, 11, 17, 55, 85, 187, 935
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,935,240,899, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
935:5x 11x 17
240:2x 2x 2x 2x 3x 5
899:29x 31
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 84728952000/(1x300)
LCM = 84728952000/300
LCM = 282429840
Thus, we can understand that the LCM of 420,935,240,899 is 282429840.
