Given numbers are 805,215,525,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,215,525,777 is 19211325.
Find LCM of 805,215,525,777 with Prime Factorization
| 3 | 805, 215, 525, 777 |
| 5 | 805, 215, 175, 259 |
| 7 | 161, 43, 35, 259 |
| 23, 43, 5, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 23 x 43 x 5 x 37 = 19211325
Therefore, the lowest common multiple of 805,215,525,777 is 19211325.
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.
805 x 215 x 525 x 777 = 70601619375
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
215 : 1, 5, 43, 215
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,215,525,777, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
215:5x 43
525:3x 5x 5x 7
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 7x 7 = 3675
Therefore, the value for common factors is 3675.
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 = 70601619375/(1x3675)
LCM = 70601619375/3675
LCM = 19211325
Thus, we can understand that the LCM of 805,215,525,777 is 19211325.
