Given numbers are 805,315,269,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,315,269,144 is 31182480.
Find LCM of 805,315,269,144 with Prime Factorization
| 3 | 805, 315, 269, 144 |
| 3 | 805, 105, 269, 48 |
| 5 | 805, 35, 269, 16 |
| 7 | 161, 7, 269, 16 |
| 23, 1, 269, 16 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 23 x 1 x 269 x 16 = 31182480
Therefore, the lowest common multiple of 805,315,269,144 is 31182480.
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 315 x 269 x 144 = 9822481200
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
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
269 : 1, 269
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,315,269,144, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
315:3x 3x 5x 7
269:269
144:2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 9822481200/(1x315)
LCM = 9822481200/315
LCM = 31182480
Thus, we can understand that the LCM of 805,315,269,144 is 31182480.
