Given numbers are 840,795,327,900
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,795,327,900 is 72790200.
Find LCM of 840,795,327,900 with Prime Factorization
| 2 | 840, 795, 327, 900 |
| 2 | 420, 795, 327, 450 |
| 3 | 210, 795, 327, 225 |
| 5 | 70, 265, 109, 75 |
| 14, 53, 109, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 14 x 53 x 109 x 15 = 72790200
Therefore, the lowest common multiple of 840,795,327,900 is 72790200.
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.
840 x 795 x 327 x 900 = 196533540000
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
795 : 1, 3, 5, 15, 53, 159, 265, 795
327 : 1, 3, 109, 327
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
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,795,327,900, is 3.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
795:3x 5x 53
327:3x 109
900:2x 2x 3x 3x 5x 5
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 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 196533540000/(3x900)
LCM = 196533540000/2700
LCM = 72790200
Thus, we can understand that the LCM of 840,795,327,900 is 72790200.
